Tim Newsome 39716b15ab Fix authentication for multi-core targets.
When authdata_write sets the authenticated bit, examine() every OpenOCD
target that is connected to the DM that we were authenticated to.

Tim Newsome 10108b623d Add `authdata_read` and `authdata_write` commands.
They can be used to authenticate to a Debug Module.

There's a bit of a chicken and egg problem here, because the RISCV
commands aren't available until the target is initialized, but
initialization involves examine(), which can't interact with the target
until authentication has happened. So to use this you run `init`, which
will print out an error, and then run the `riscv authdata_read` and
`riscv authdata_write` commands. When authdata_write() notices that the
authenticated bit went high, it will call examine() again.

Example usage (very simple challenge-response protocol):
```
init

set challenge [ocd_riscv authdata_read]
riscv authdata_write [expr $challenge + 1]

reset halt
```

Tomas Vanek bae76053dc gdb_server: run control fixes for vCont
this patch contains several changes to run control and state
handling together with gdb:
- graceful handling of target/gdb desync on resume, step and halt
- a default gdb-attach event executing the "halt" command, to meet gdb
  expectation of target state when it attaches
- call target_poll() after Ctrl-C command from gdb
- call target_poll() after resume and step through a vCont packet
- fix log message forwarding on vCont stepping, also move an aarch64
  log message from INFO to DEBUG level to prevent messing up the gdb
  console during source-line stepping
- fix oversight in vCont support that messes up breakpoint handling
  during stepping

flash_write_unlock() sorts sections by base address but does not check
if they overlap. In case of overlapped sections an item of padding[]
array can get negative and padding loop writes out of allocated buffer.

How to replicate: cat two copies of an ihex file to one file and try
to flash it.

Check for overlapped sections and abort write in such case.

Matthias Welwarsky 293fb9b25f rtos: facilitate RTOS SMP handling
The RTOS handlers present OS threads to gdb but the openocd
target layer only knows about CPU cores (hardware threads).
This patch allows closing this gap inside the RTOS handler.

The default implementation just returns the current core, but
a RTOS handler can provide its own function that associates a
an OS thread with a core.

Matthias Welwarsky b551c62a7f cortex_a: fix handling of Thumb-2 32bit breakpoints
When debugging Thumb-2 code, Gdb will at times send a
breakpoint packet 'Z0,<addr>,3', the number 3 denoting that
the instruction to break on is 32 bits long. Handle this by
replacing it with two consecutive 16bit Thumb BKPTs and make
sure to save and restore the full, original 32bit
instruction.

Note that this fix is only applicable if you debug a bare-metal program
(like the linux kernel) with the 'wrong' gdb, e.g. use an 
"arm-linux" gdb instead of an "arm-eabi" gdb. But since most people
may not know about the subtle differences between gdb configurations
regarding thumb2 breakpoints it's still valid.

Jonas Norling 6d390e1b2a efm32: Refactor EFM32 chip family data, add more chips
Add support for more EFM32/EFR32 Series 1 families. The family IDs
come from the DEVICE_FAMILY list in the EFM32GG11 reference manual,
which is the most up to date source I could find. Register locations
have been checked against SiLab's header files.

No datasheets or headers were available for EFR32MG2, EFR32xG14 and
EFM32TG11B, so they are just assumed to follow the pattern. EFM32GG11B
has the MSC registers on a different address compared to other chips.

This commit attempts not to change current behavior when detecting
chips. One detail that has changed is that PAGE_SIZE is read before
applying the workaround for old Giant and Leopard Gecko revisions, but
this is believed to be OK because the register exists but just has an
invalid value in it.

The manuals disagree on which of 120 and 121 is WG, so this commit
leaves it as is.

- fixed endianess problem in flash write and protection setting
- removed fancy chip detection table as it would be updated too often
- psoc4 flash_autoerase is now on by default to ease programming

Tim Newsome 64f1f7b1c1 Add read buffer to bitbang, improving performance.
Previously for every bit scanned OpenOCD would write the bit, wait for
that bit to be scanned, and then read the result. This involves at least
2 context switches. Most of the time the next bit scanned does not
depend on the last bit we read, so with a buffer we now write a bunch of
bits to be scanned all at once, and then we wait for them all to be
scanned and have a result.

This reduces the time for one testcase where OpenOCD connects to a
simulator from 12.30s to 5.35s!

Running all our tests went from 13m13s to 3m55s.

Tomas Vanek e3f3b77729 flash Kinetis: make FCF protection more user friendly
The Flash Configuration Field on Kinetis devices requires protection
because it is located in program flash space (at 0x400) and writing
an improper data to it may permanently lock the device. Even an erased
flash sector containing FCF engages security lock (not permanent one)
on the next reset or power cycle.

'kinetis fcf_source protection' mode was introduced in the change #3562.
Flash driver in this mode sets FCF immediately after sector erase to
prevent unintentional security lock. To do so the driver needs to know
FCF values before flash image data is actually processed. Flash
protection bits are available in bank structure, FOPT can be set by
'kinetis fopt' command and securing device by FSEC is not supported.

Nevertheless an inexperienced user flashed the device using an image
with FCF values different from those set in OpenOCD config and
concluded programming did not work as some verify errors showed.

This change tries to write maximum possible from image data
retaining FCF protection.

Check FCF in programmed data and report if some field differs from
values set by OpenOCD flash block protection and 'kinetis fopt' command.
Warn user about verify errors caused by FCF protection.

On devices with ECC flash (K26, K66 and KV5x) it is impossible to change
already programmed FCF - it would result in an ECC error. As FCF was
written just after erase in 'kinetis fcf_source protection' mode
the warning issued during flash write is the only possible action.

On non-ECC flash devices use cumulative flash programming to
set FCF values requested in programmed image data.
Use FSEC from programmed data only if it does not request a secure
mode. Device can be secured only in 'kinetis fcf_source write' mode.
Use FOPT from programmed data if its value was not configured
in OpenOCD config by 'kinetis fopt' command.

Robert Jordens 867bdb2e92 jtagspi: new protocol that includes transfer length
This commit contains a rewrite of the jtagspi protocol and covers both
changes in the jtagspi.c openocd driver and the bscan_spi
(xilinx_bscan_spi) proxy bitstreams. The changes are as follows:

1. Always perform IR scan to ensure proper clearing of BYPASSed DRs.
2. Insert alignment cycles for all BYPASSed TAPs:

  The previous logic was erroneous. The delay in clock cyles from a bit
  written to the jtag interface to a bit read by the jtag interface is:

  * The number of BYPASSed TAPs before this (jtagspi) tap
  * The length of the jtagspi data register (1)
  * The number of BYPASSed TAPs before this one.

  I.e. it is just the number of enabled TAPs. This also gets rid of the
  configuration parameter DR_LENGTH.

3. Use marker bit to start spi transfer

  If there are TAPs ahead of this one on the JTAG chain, and we are in
  DR-SHIFT, there will be old bits toggled through first before the first
  valid bit destined for the flash.
  This delays the begin of the JTAGSPI transaction until the first high bit.

4. New jtagspi protocol

  A JTAGSPI transfer now consists of:

  * an arbitrary number of 0 bits (from BYPASS registers in front of the
    JTAG2SPI DR)
  * a marker bit (1) indicating the start of the JTAG2SPI transaction
  * 32 bits (big endian) describing the length of the SPI transaction
  * a number of SPI clock cycles (corresponding to 3.) with CS_N asserted
  * an arbitrary number of cycles (to shift MISO/TDO data through
    subsequent BYPASS registers)

5. xilinx_bscan_spi: clean up, add ultrascale

This is tested on the following configurations:

* KC705: XC7K325T
* Sayma AMC: XCKU040
* Sayma AMC + RTM): XCKU040 + XC7A15T, a board with integrated FTDI JTAG
  adapter, SCANSTA JTAG router, a Xilinx Ultrascale XCKU040 and a Xilinx
  Artix 7 15T. https://github.com/m-labs/sinara/wiki/Sayma

Felipe Balbi 1ea313e333 target: lakemon: probemode entry isn't instantaneous
When testing with Intel Galileo GEN2 I have noticed a few iterations
where probemode entry took a little longer. At most I had to read
tapstatus twice. This patch uses a loop of up to 100 iterations to
wait for tapstatus to update with PM entry results.

Ake Rehnman 3de6b5f6e5 jtag/drivers/stlink_usb : implemented and repaired SWIM support
Fixed a bug in stlink_usb_read_mem/write_mem preventing large data transfers

The SWIM support in stlink_usb was basically non existent so I have
implemented the missing parts. The bCBWCBLength and dCBWDataTransferLength
for STLINK-V1 protocol was not correct so that was fixed. The reason for
adding SWIM support is to add STM8 support for OpenOCD.

I have tested the driver on:
STM8 discovery board with the built-in STLINK-V1
STM8 discovery board with STLINK-V2 dongle
STM32 vldiscovery board with the built-in STLINK-V1
STM32F1xxx processor with STLINK-V2 dongle

Tomas Vanek 4553abf906 arm_adi_v5: fix wrong addressing after change of CSW_ADDRINC
Problem: If the same memory location is accessed alternatively
by MEM-AP banked data registers without autoincrement and by standard
autoincremented read/write, TAR register is not updated correctly.

How to replicate: On a Cortex-M issue
    mdw 0xe000edf0
multiple times. When poll is on (poll reads the same memory location)
only the first read is correct.
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 20002640
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 00000000

No problems with poll off.
0xe000edf0: 01000000
0xe000edf0: 01000000
0xe000edf0: 01000000

mem_ap_setup_tar() writes to MEM_AP_REG_TAR if requested TAR value
changed or CSW_ADDRINC_... is currently active.
However if an autoincremented access has been issued and autoinc
switched off in CSW afterwards, TAR does not get updated.

The change introduces mem_ap_update_tar_cache() which is called
after queuing of any access to MEM_AP_REG_DRW. It simulates
TAR increment to keep tar_value in sync with MEM_AP.
Crossing tar autoincrement block boundary invalidates cached value.

mem_ap_write() and mem_ap_read() do not check tar autoincrement
block boundary, mem_ap_setup_tar() is called before each transfer instead.

dap_invalidate_cache() is introduced to ensure invalidation
of all cached values during dap_dp_init() and swd_connect()

Bas Vermeulen ada631cc5f target aarch64: rework memory read/write to use 8/16/32 bit operations
The existing code only used Memory Access mode to read memory,
which uses 32 bit operations only.
Rework the code to check the alignment/size of the read/write operation,
and use the Memory Access mode to read aligned 32 bit memory.
When using unaligned access, or 8 or 16 bit reads, use LDR{BHW} and STR{BHW}
instead.

The exception handling is still the same as it was before (meaning it breaks
when things go wrong), but I can now read an 8 bit register correctly.

Tomas Vanek bb976e3c38 jtag/drivers/cmsis-dap: fix connect under reset
Commit ef02b69b14 included
a call to cmsis_dap_cmd_DAP_Connect() before calling
cmsis_dap_cmd_DAP_SWJ_Sequence(). According to comment
it is necessary for at least Keil ULINK-ME.

Commit 72c3464be4 added
a cmsis_dap_cmd_DAP_Disconnect() before connect call to pair
connection/disconnection. It solves some problems on Atmel EDBG.

Unfortunately calling either of cmsis_dap_cmd_DAP_Connect()
or cmsis_dap_cmd_DAP_Disconnect() deasserts reset signal.
So these workarounds break ability to connect under reset.

Use cmsis_dap_cmd_DAP_Disconnect() and cmsis_dap_cmd_DAP_Connect()
pair only if both SRST and TRST are deasserted.

Tim Newsome db754536e8 Support 64-bit FPRs on RV32.
Because there is no instruction that moves just half of a 64-bit FPR
to/from a GPR, we need to use scratch memory for this operation. This
code can theoretically use:
1. DMI_DATA, if it is memory mapped in the target.
2. DMI_PROGBUF, if it is writable in the target.
3. A user-configured address.

I have only tested this code very lightly. One reason is that gdb thinks
that on RV32 harts every register is 32 bits wide. Another is that this
is mostly proof-of-concept to satisfy the small program buffer code
review, which I don't want to drag out forever.

Existing tests don't realize that floating support was broken with
RV32D, and don't realize that it still doesn't work because of the gdb
problem mentioned above.

This change improves Issue #110 but there's more work to be done.

The SWDIO buffer has to be enabled, by setting SWDIO_OE, for data on
SWDIO to reach the target. Explicitly do this before sending the
switch sequences for JTAG-to-SWD, etc.

This makes the code insensitive to the state of SWDIO_OE specified in
ftdi_layout_init. It used to work only on adapters with a non-inverted
SWDIO_OE inited to 1, or inverted SWDIO_OE inited to 0.

The dhcsr_save variable was used to save the value of
cortex_m->dcb_dhcsr so it could be restored later. However, all writes
in between the save and the restore use mem_ap_write_atomic_u32, not
cortex_m_write_debug_halt_mask, which means cortex_m->dcb_dhcsr isn’t
changed anyway. Delete the unnecessary local.

Christopher Head 02df0abb54 Cortex-M: fix stale DHCSR cache values
In cortex_m_assert_reset, in two locations, DHCSR is written directly
using mem_ap_write_u32. This means that the cached version,
target_to_cm(target)->dcb_dhcsr, is not updated when these writes are
performed, so subsequent writes to DHCSR that use
cortex_m_write_debug_halt_mask will change those bits back to their old
values which, unless modified in that particular invocation, come from
the cache. This causes an actual, observable bug on an STM32F7 in which
running “reset run” immediately after “program” can in some cases result
in execution proceeding with C_MASKINTS set (it is cleared on line 1021
but is then set immediately afterward in cortex_m_clear_halt), causing
failure of the application. Replace these mem_ap_write_u32 calls with
cortex_m_write_debug_halt_mask calls to do the same jobs.

Karl Palsson bf5258d876 telnet_server: increase buffer sizes to allow longer commands.
A common use case seen in the wild is echoing a string of commands to an
existing openocd instance via netcat.  The sequence of ; separated
commands can easily run over the line limit of only 256 chars.

Increasing this dramatically reduces surprises, at the expense of a tiny
amount of extra ram usage.

memory read is now completely stable even on intermittently slow targets
2017-08-29 17:33:51 -07:00
Tim Newsome 6721988ce3 Ensure read_memory() only reads each address once.
Previously it might read an address multiple times if an abstract
command took longer to execute than expected.

The new implementations reads from the target how far it has gotten
along reading memory, and resumes from there if cmderr=busy.

This ended up being a bigger change than I envisioned, but in the end it
deleted more lines than it added, so I'm happy. :-)
2017-08-29 17:25:04 -07:00
Tim Newsome 2efc415db4 Finally nailed memory read on slow targets
The downloaded program now post-increments, and there's no longer an
attempt to read the current address from the target. This made it easier
to fix the problem where at the start of the loop the current address
was already read (in regular entry) or has not yet been read (when the
first round through the loop encountered busy more than once, or busy
was encountered at least once later on).

Andreas Bolsch 7719e9618e Support for STM32F722, F723, F413 and F423
IDs for STM32F722, F723, F413 and F423 added, handling of PCROP
for F722/723 and additional nWPRT bits for F413/423 implemented.
The additional protection bit positions for F413/423 conflict
with other options bits for the F7xx variants, additionally the
last two sectors share a common bit.

Protection for F413 and F767/777 now use protection blocks
rather sectors for dealing with protections bits.

Checking for halted state in 'lock' and 'unlock' removed: When
PCROP is activated in F723, halted state is not detected properly,
but lock/unlock sequence is required to disable PCROP.

Tested with STM32F723E-Disco, STM32F413ZH-Nucleo.

The change limits the test to devices without FlexNVM.

This is the only way the spec guarantees that GPRs are accessible, and
depending on the implementation this might be the only way that CSRs are
accessible.

Also changed the debug code that parses out DMI fields to be simpler to
maintain (albeit a little slower).

riscv013_execute_debug_buffer() now automatically clears cmderr if the
command fails. That feels like the right behavior. (It does return the
error to its caller.)

Tim Newsome 4072fa493b Disable debugger-set triggers on connect
When first connecting to a target, have the debugger disable any
hardware triggers that are set by a previously connected debugger.
The 0.11 code already did this, but 0.13 did not.

To achieve this I decided to share the code to enumerate triggers
between 0.11 and 0.13, which required me to implement get_register() and
set_register() for 0.11, which made the whole change a lot larger than
you might have guessed.

Hopefully this sets us up to in the future share the code to set/remove
triggers as well.

Tomas Vanek 5a2608bbbc flash Kinetis: handle all types of watchdog, disable in reset-init
Active watchdog forces reset during armv7m_checksum_memory()
in verify_image command if run just after reset init.

COP watchdog in KL series and WDOG32 in KE1 series
have longer timeout however they need to be disabled too.

The change extends 'kinetis disable_wdog' command to optionally
probe the chip and use appropriate algorithm to disable watchdog.

Setting of cache type is also split from flash_support flags.

Tcl command 'kinetis disable_wdog' is called in reset-init event.

Tomas Vanek c4d4c32a50 flash Kinetis: implement automatic bank creation based on device probe
Kinetis flash driver services huge number of MCU types. They have
one, two or four flash banks with option of FlexNVM. It would
require ~36 config files just for Kx series, more for KLx, KVx and KE1x.

The change implements alternative approach:
- configuration file creates just one pflash bank (common for all devices)
- when a device is probed, additional pflash or flexnvm banks are created
based on flash layout of the connected MCU
- created banks have names with optional numbering e.g. kx.pflash0 kx.pflash1
kx.flexnvm0 kx.flexnvm1
- the first bank gets renamed if numbering is used

Automatic bank creation is enabled by tcl command 'kinetis create_banks'.

Used solution has a drawback: other banks than pflash0 are not accessible
until pflash0 is probed. Fortunately gdb attach and standard programming
accesses banks in right sequence.

Tomas Vanek 1fdc62ef65 flash Kinetis: split kinetis_chip from kinetis_flash_bank
Kinetis flash driver probed and decoded chip repeatedly for each flash
bank. Bank ordering used global bank number so multi-target
configuration was broken.

The change introduces kinetis_probe_chip() which reads SIM SDID
and SIM FCFG registers, decodes Kinetis series and family
and fills struct kinetis_chip. This probe runs once for all banks.

struct kinetis_chip contains pointers to all flash banks embeded
in the MCU. It simplifies iteration over all or specific MCU banks.

kinetis_probe_chip() generates MCU name and some informational messages
are improved.

Tobias Diedrich 6b9d19d367 flash: Add support for Atheros (ath79) SPI interface
Supported SoCs: AR71xx, AR724x, AR91xx, AR93xx, QCA9558

Extended and revised version of my original patch submitted by Dmytro
here: http://openocd.zylin.com/#/c/3390

This driver is using pure SPI mode, so the flash base address is not
used except some flash commands (e.g. "flash program") need it to
distinguish the banks.

Example config with all 3 chip selects:
flash bank flash0 ath79 0 0 0 0 $_TARGETNAME cs0
flash bank flash1 ath79 0x10000000 0 0 0 $_TARGETNAME cs1
flash bank flash2 ath79 0x20000000 0 0 0 $_TARGETNAME cs2

Example usage:
> flash probe flash0
Found flash device 'win w25q128fv' (ID 0x001840ef)
flash 'ath79' found at 0x00000000
> flash probe flash1
No SPI flash found
> flash probe flash2
No SPI flash found
> flash banks
> flash read_bank flash0 /tmp/test.bin 0x00000000 0x1000

Palmer Dabbelt 8dea2908b7 Add 64-bit and multihart support
This is a major rewrite of the RISC-V v0.13 OpenOCD port.  This
shouldn't have any meaningful effect on the v0.11 support, but it does
add generic versions of many functions that will allow me to later
refactor the v0.11 support so it's easier to maintain both ports.  This
started as an emergency feature branch and went on for a long time, so
it's all been squashed down into one commit so there isn't a big set of
broken commits lying around.  The changes are:

 * You can pass "-rtos riscv" to the target in OpenOCD's configuration
   file, which enables multi-hart mode.  This uses OpenOCD's RTOS
   support to control all the harts from the debug module using commands
   like "info threads" in GDB.  This support is still expermental.

 * There is support for RV64I, but due to OpenOCD limitations we only
   support 32-bit physical addresses.  I hope to remedy this by rebasing
   onto the latest OpenOCD release, which I've heard should fix this.

 * This matches the latest draft version of the RISC-V debug spec, as of
   April 26th.  This version fixes a number of spec bugs and should be
   close to the final debug spec.

CezaryGapinski e916bcda64 stm32lx: fix dual-bank configuration for Cat.5 and Cat.6 devices
Default values for .first_bank_size_kb and .has_dual_banks fields
described in stm32lx_parts[] do not fully describe
the real device memory layouts.

Basing on:
STM32L0x1 RM0377
STM32L0x2 RM0376
STM32L0x3 RM0367
STM32Lxxxx RM0038

correct values for memory layouts were selected:
id = 0x447 STM32L0xx (Cat.5) <- dual bank flash
for size 192 or 128 KBytes, single bank for 64 KBytes
id = 0x436 STM32L1xx (Cat.4 / Cat.3 - Medium + /
High Density) <- only one size of the bank,
default values are correct
id = 0x437 STM32L1xx (Cat.5 / Cat.6) <- always dual bank,
but size of the bank can be different

For that reason .part_info field in struct stm32lx_flash_bank
is a dynamic field with fields copied from stm32lx_parts[]
and overwriten to correct values
for specific chips and memory sizes.

Austin Morton 568e84236b stlink: increase trace buffer size to maximum allowed on st-link v2 firmware
Increasing the trace buffer size on the st-link itself gives openocd a greater
chance of avoiding trace data overflowing within the st-link between polls
when there is a large amount of data being sent over the trace port

The st-link appears to split the given buffer size in half
while one half is awaiting transfer over USB, the other half is being
filled by DMA transfer.  If you do not poll frequently enough, the DMA
transfer will overflow back to the start of its current buffer, resulting in
corrupted output

Buffer size of 4096 bytes is the maximum allowed by the st-link v2

Matthias Welwarsky bf1efe05bb aarch64: run control rework
This patch contains a major overhaul of the target run control,
mainly for the sake of satisfying gdbs ideas of how a target
should respond to various control requests for the debugger.

The changes allow gdb a slightly better control on how cores
are stepped: a core can be single-stepped while 
other cores remain halted or continue normal execution 
until the single-stepped core halts again.

Also, on any halting event (user command or breakpoint) the
system is brought into a stable state with all cores halted
before the halt is signaled to the debugger.

This patch also transitions the target code to make use of the
new CTI abstraction instead of accessing CTI registers directly.

Tim Newsome 3bd661b679 Speed things up by ignoring return values.
The remote bitbang implementation is really slow when reading back data.
During many operations, like writing a block of memory, we don't need to
see the return data. By communicating this to the lower layers, we get
huge speedups. Downloads to spike now are 295KB/s.

That means the gdbserver.py download test now runs to completion,
unfortunately it fails. Everything else is still passing, though, so I'm
committing this change.

Matthias Welwarsky c30f8d6a07 aarch64: handle exceptions taken in debug state
When an armv8-a PE causes an exception while halted, e.g. by performing
a prohibited memory or register access, its state is affected in the
same way as if it was running. That means, a number of registers is
overwritten (notably DLR and DSPSR, but also others) and also
potentially the exception level and therefore also the PE state can
change. This state must be restored before resuming normal operation.

This is done by marking the relevant cached registers "dirty" so that
they are written back before resume.

All register access is now performed through common read/write
functions, which delegate the actual register access to the
armv8_common object. armv8_common contains function pointers
to direct read and write requests to the respective low-level

The respective read/write functions are selected on debug state
entry.

At the same time, T32 opcodes are now formatted for ITR in
dpmv8_exec_opcode() and the T32_FMTITR macro is removed from global
visibility.

This should be made configurable, like on cortex_a target.

an ARMv8 core and therefore it's always present (and required),
regardless of the ROM table listing it or not.

David Ung 6b554b3b0e aarch64: Correct target state for hardware step
When using hardware step for doing stepping, the existing DSCR records
the event as external debug request.  This will generate a SIGINT event
to GDB and causes it to stop the stepping process.
For aarch64, read DESR to check if the event is a hardware step and set
state to DBG_REASON_SINGLESTEP.
With this patch, GDB can now do source level stepping.

Dongxue Zhang 47b8cf8420 target: Add 64-bit target address support
Define a target_addr_t type to support 32-bit and 64-bit addresses at
the same time. Also define matching TARGET_PRI*ADDR format macros as
well as a convenient TARGET_ADDR_FMT.

In targets that are 32-bit (avr32, nds32, arm7/9/11, fm4, xmc1000)
be least invasive by leaving the formatting unchanged apart from the
type;
for generic code adopt TARGET_ADDR_FMT as unified address format.

Don't silently change gdb formatting here, leave that to later.

Add COMMAND_PARSE_ADDRESS() macro to abstract the address type.
Implement it using its own parse_target_addr() function, in the hopes
of catching pointer type mismatches better.

Add '--disable-target64' configure option to revert to previous 32-bit
target address behavior.

Andreas Fritiofson 6ddf26c83d Search for scripts relative to the executable on all(?) platforms
Add a helper to hide the platform-dependent method to get a
canonical, absolute, /-separated path to the executable.

Use this and the relative path from BINDIR to PKGDATADIR to
construct a search path that finds the scripts even if the
installation dir is moved, as long as the structure below $prefix
is maintained.

This method should fully support all the tricks you can to with
autotools to customize the installed layout such as overriding the
default directories at configure-time and overriding the configured
directories at build-time.

The exe path detection methods are combined from
http://openocd.zylin.com/3388 by Rick Foos and
http://openocd.zylin.com/3537 by Steven Stallion, as well as tips

Libusb (1.x or 0.1) is now a hard dependency of the openjtag driver.
This should not be a big issue as libftdi also depends on it.

Steven Stallion 50dd7207ea gdb_server: support qXfer:threads:read packet
This patch adds support for the qXfer:threads:read packet. In addition
to providing a more efficient method of updating thread state, recent
versions of GDB (7.11.1 and up) can also report remote thread names.
While thread names are not enabled in this patch due to its limited
applicability at the moment, it can be enabled at a later date with
little effort.

As a part of revamping how threads are presented to GDB, extra info
strings for each of the supported RTOSes were updated to match
conventions present in the GDB source code. For more information, see
remote_threads_extra_info() in remote.c. This results in a much smoother
experience when interacting with GDB.

It is also worth mentioning that use of qXfer:threads:read works around
a number of regressions in older versions of GDB regarding remote thread
display. Trust me, it's great.

Steven Stallion c0e7ccbd87 semihosting: support fileio operation
This patch adds support for bridging semihosting to GDB's File-I/O
remote protocol extension. For the most part operations match up 1:1,
however some require a working area to complete successfully, namely
operations that devolve to read, stat, and gettimeofday.

A new command was added to enable support for fileio named `arm
semihosting_fileio`, which ensures that the default behavior remains
intact for those that prefer it.

Finally, redundant logging was removed from the target_arch_state
function; this permits ARM targets to quiesce log output when polling
for a fileio reply. This prevents filling the logs with halt/resume
messages when using semihosting fileio.
