Karl Palsson 4e0371bf71 hla_target: allow non-intrusive profiling on cortex-m
Leverages the existing work that added profiling via DWT_PCSR.

hla_target doesn't have direct access to the mem_ap for doing a bulk
repeated read, but simply reading the DWT_PCSR register repeatedly is
still ~2 order of magnitude faster than halt/resume.

Felipe Balbi 2b44b52478 target: lakemon: implement assert_reset and deassert_reset
We're using an I/O port reset by default. The only board currently
supported (Galileo) doesn't have SRST routed on the JTAG connector.

When using 'reset halt', we must rely on Reset Break because our
adapters don't have support for PREQ#/PRDY# signals.

Tested with Intel Galileo GEN2.

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.

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.

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

Salvador Arroyo 2279c23cde mips32, add support for micromips in debug mode
Micromips is 16bit oriented, branch and jumps are
16 bit based. The upper half 16bits of a 32bit instruction
with the major opcode, must go first in the instruction
stream, hence the SWAP16 macro and swap16 array function,
needed if the code is written as 32 bit word in little endian
cores. Endianess info added to ejtag_iinfo. Pointer to
ejtag_info and isa field added to pracc context.
MIPS32 code are renamed to MIPS32_ISA_...
To select the isa, the new code has an additional isa parameter
(1 for micromips, 0 for mips32).
In JR instruction the isa bit must be set to execute
micromips code.
The suffix u is added to the OP codes to avoid signed/unsigned
comparison errors and to make sure the right shift is
performed logically.
The isa in debug mode is updated in the poll function.
Code for miniprograms, in kernel mode, need to be converted.
CFI code only for mips32.

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.

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.

On live hardware, interrupts will happen while the core is
held for stepping. The next step will most of the time execute an

for a step, and re-enable them again after the step happened.

This should be made configurable, like on cortex_a target.

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.

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.

Matthias Welwarsky 0a2f1b29e6 cortex_a: remove partnum magic from arp_examine and dbginit
Depending on the Debug implementation the "OS Lock" feature might be
implemented or not. It is not actually depending on the part number of the
implemented ARM core but on the DBGOSLSR.OSLM bits. This patch removes
querying the part number and implements proper parsing of OSLM. Result is
a more generic approach that will work out-of-box on more devices.

Matthias Welwarsky 53a936afc0 Add -defer-examine option to target create command
The '-defer-examine' option to target create allows declaring targets
that are present on the chain, but not fully functional.  They will
be skipped by the initial arp_examine as well as arp_examine after
reset.

Manual examine using 'arp_examine' is needed to examine them, with the
idea that some kind of actions is neeed to bring them to a state where
examine will succeed (if at all possible).

In order to allow value less options to target command, I had to relax
the goi.argc check in jim_target_configure().

Flash erase_sector command :

retval value should be returned.

Flash write_bank command :
handle_flash_write_bank_command() returns ERROR_OK even if

returned.

Load_image command :

When the buffer is null, breaking the loop without setting
retval = ERROR_FAIL would cause load_image to return ERROR_OK.

Andreas Färber eaacb900dd flash/nor: Add erased_value to drivers and pass it to targets
struct flash_driver has a default_padded_value field that is similar,
but it can be changed by the user for the specific purpose of padding.

Add a new erased_value field and initialize it for all targets,
particularly stm32lx, xmc4xxx and virtual.

Use this value in core.c:default_flash_mem_blank_check(), the slow path.

Extend the target API to pass erased_value down to target code.
Adding an argument ensures that we catch all callers.

This allows us to merge xmc4xxx.c:xmc4xxx_blank_check_memory() into
armv7m:armv7m_blank_check_memory().

It further allows us to use default_flash_blank_check() in place of
xmc4xxx.c:xmc4xxx_flash_blank_check(), adding a potential slow path
fallback, as well as stm32lx:stm32lx_erase_check(), adding the potential
armv7m fast path with fallback to default_flash_mem_blank_check().

Fix a mips32 code comment while at it (zeroed -> erased).

The armv4_5 and mips32 target implementations will now error out if an
erase value other than 0xff is used, causing default_flash_blank_check()
to fall back to the default_flank_mem_blank_check() slow path.

Sometimes it is necessary to resume into a different state (ARM/Thumb)
than at debug state entry. According to the documentation this should
be possible with "arm core_state arm|thumb" before the resume command,
however the original code also restores the original CPSR, which
overrides whatever state the core was set to. This seems to work on some
cores (e.g. Cortex-A5) but not on others (e.g. Cortex-A9). Using the "BX"
instruction to set resume PC and core state works on Cortex-A9 and
ARM11, but is not sufficient on Cortex-A5, where an explicit write to
the PC (MOV pc, r0) is required additionally.

the CPU (which happens to be controlled over the APB-AP). Rename all
irrelevant uses of the APB-AP term. And fix the long standing typo in
the function names...

Tomas Vanek 8825804273 target: improve robustness of reset command
Before this change jim_target_reset() checked examined state of a target
and failed without calling .assert_reset in particular target layer
(and without comprehensible warning to user).
Cortex-M target (which refuses access to DP under active SRST):
If connection is lost then reset process fails before asserting SRST
and connection with MCU is not restored.
This resulted in:
1) A lot of Cortex-M MCUs required use of reset button or cycling power
after firmware blocked SWD access somehow (sleep, misconfigured clock etc).
If firmware blocks SWD access early during initialization, a MCU could
become completely inaccessible by SWD.
2) If OpenOCD is (re)started and a MCU is in a broken state unresponsive
to SWD, reset command does not work even if it could help to restore communication.
Hopefully this scenario is not possible under full JTAG.

jim_target_reset() in target.c now does not check examined state
and delegates this task to a particular target. All targets have been checked
and xx_assert_reset() (or xx_deassert_reset()) procedures were changed
to check examined state if needed. Targets except arm11, cortex_a and cortex_m
just fail if target is not examined although it may be possible to use
at least hw reset. Left as TODO for developers familiar with these targets.

cortex_m_assert_reset(): memory access errors are stored
instead of immediate returning them to a higher level.
Errors from less important reads/writes are ignored.
Requested reset always leads to a configured action.

arm11_assert_reset() just asserts hw reset in case of not examined target.
cortex_a_assert_reset() works as usual in case of not examined target.

Matthias Welwarsky b6c4a5db3e cortex_a: allow physical memory access through AHB-AP again
This feature is required for boards that use a programmatical way
to reset the cpu, like the TI Pandaboard with OMAP4. The board only
has a 14 pin JTAG header that doesn't feature SRST and is reset by
direct write to the PRM_RSTCTL register.

iMX6 can be reset through triggering the on-chip watchdog, but for these
methods to work reliably, access through the AHB-AP without interaction
with the CPU core is necessary.

Matthias Welwarsky 5373085b4d adiv5: introduce optional dap_sync() function
dap_sync() executes all commands in the JTAG queue and then checks
if a WAIT condition happened inside the last batch. If yes, a recovery
is invoked. If not, processing continues without checking for
errors. This function should be called in long AP read or writes, e.g.
while uploading a new application binary, at intermediate points within
the transfer where the cost of flushing the JTAG queue and checking the
journal doesn't affect performance too much.

Matthias Welwarsky a185eaad9d adi_v5_jtag: implement DAP WAIT support
ADIv5 specifies that DP and AP accesses may generate a WAIT
response when the hardware is not able to complete a request for various
reasons in time before the next request is sent. Currently, the software
treats a WAIT response as a fatal error and aborts operation on the DAP.

This patch implements WAIT handling by keeping a journal of all
outstanding and completed accesses, including their response status.
At certain times (when dap_run() is called), the journal is inspected
for WAIT responses and all discarded accesses are replayed to complete
them. Special care is taken to not re-execute already successfully
completed operations.

Peter Lawrence 2f131d3c30 ARM ADIv5: CoreSight ROM decode part number and designer id
The existing arm_adi_v5.c code decodes CoreSight peripherals based
on the part number field.  However, these are specific to a
particular manufacturer (often ARM).  The same part number from
two different manufacturers (distinct designer ids) should not
decode as the same CoreSight peripheral.

The Analog Devices ADSP-SC58x and ADSP-BF70x have peripherals that
overlap with existing OpenOCD decoding.  The part number is the
same as existing OpenOCD decoding, but have a different JEP106 code.

Most, if not all, of the existing part number entries in
arm_adi_v5.c are probably specific to ARM. Change all entries
suspected to be designed by ARM to match only ARM's designer ID.

However, to preserve legacy behavior, existing non-ARM entries are
encoded with a wildcard so that they will behave in the same way as
the existing legacy code.  It is desirable, however, to start
encoding the data with designer codes to avoid such ambiguity.

Revising the code to check both the part number and designer id
seemed to a warrant a const array lookup table instead of a
multi-tiered switch statement.

Also try to sync part identification IDs with relevant ARM docs.

Matthias Welwarsky 464f7005bb arm_debug: optimize DP and AP reads over JTAG
On JTAG, all reads are pipelined. If you read a register, the result is not
delivered inside the request that issued the read, it is delivered in the
following request. The current code therefore issues a scan of the RDBUFF
register after each read. This adds a superfluous transaction after each
read.

This patch follows a strategy similar to what SWD already implements.
It also leverages that all JTAG reads are pipelined, i.e. the result
will be clocked out in the next JTAG data phase, no matter if it's
READ or WRITE. Therefore it's never necessary to explicitly read RDBUFF
other than for the very last READ before a dap_run().

Debug initialization blindly selects AP#0 as default, which is the AHB-AP

However, AHB-AP is the wrong choice, because it bypasses caches on read

caches). This patch explicitely selects the APB-AP (debug_ap) as the
default.

Matthias Welwarsky 332023fb23 cortex_a: fix fast-mode memory reads
cortex_a_read_apb_ab_memory_fast() uses the wrong order of ITR and DSCR
writes when setting up the transfer. ARM DDI0406C says in C8.2 regarding
"Fast mode" operation to first switch to fast mode and then latch the
instruction in ITR. Current implementation first wrote ITR, causing
the instruction to be executed immediately, then switched to fast mode
without an instruction latched. Repeated reading of DTRTX didn't
execute LDC and thus replicated its current content into the whole buffer.

This patch uses the following, revised algorithm:
1) switch to non-blocking mode and issue the LDC for the first word
2) if more than one word is to be read:
 - switch to fast mode
 - latch the LDC instruction into ITR (it is _not_ executed)
 - issue (count-1) reads of DTRTX register, each read returns the current
   content of DTRTX and re-issues the latched instruction
 -> now the second-to-last word is in the buffer and the LDC for the last
    word has been issued.
3) wait for the last instruction to complete
4) switch back to non-blocking mode
5) Read DTRTX for the last (or: only) word and put it into the buffer

Matthias Welwarsky 8b140fd724 cortex_a: replace cortex_a_check_address function
When accessing memory through the ARM core, privilege levels and mmu
access permissions observed. Thus it depends on the current mode of the
ARM core whether an access is possible or not. the ARM in USR mode can
not access memory mapped to a higher privilege level. This means, if the
ARM core is halted while executing at PL0, the debugger would be
prevented from setting a breakpoint at an address with a higher privilege
level, e.g. in the OS kernel. This is not desirable.

cortex_a_check_address() tried to work around this by predicting if an
access would fail and switched the ARM core to SVC mode. However, the
prediction was based on hardcoded address ranges and only worked for
Linux and a 3G/1G user/kernel space split.

This patch changes the policy to always switch to SVC mode for memory
accesses. It introduces two functions cortex_a_prep_memaccess() and
cortex_a_post_memaccess() which bracket memory reads and writes. These
function encapsulate all actions necessary for preparation and cleanup.

must be disabled as well. Disabling the d-cache also requires a full

effectively the d-cache state does not change at all. We can therefore
save the the d-cache disabling and flushing.

This patch also simplifies the function a bit.

Alamy Liu bfba15a898 adi_v5: Fix wrong ap value
Problem
dap->ap_current is register value, not field value.
it restores invalid ap when it calls dap_ap_select(dap, ap_old) later.

* assume the current ap is 1, dap->ap_current value would be (1 << 24).
ap_old = dap->ap_current;   <-- ap_old = 1<<24 = 0x1000000.
...
dap_ap_select(dap, ap_old); <-- select 0x1000000, not 1.
* All AP registers accessing fail afterwards.

One of the reproducible case(s): CORE residents in AP >= 1
  dap_lookup_cs_component() being used to find PE(*).
  In most cases, PE would be found in AP==0, hence the problem is hidden.
  When AP number is 1, dap->ap_current would have the value of 1<<24.
  Anyone get the AP value with dap->ap_current and resotre it later would
  select the wrong AP and all accessing later would fail.

  The ARM Versatile and/or FPGA would have better chance to provide this
  kind of environment that PE residents in AP>=1. As they have an 'umbrella'
  system at AP0, and main system at AP>=1.

  * PE: Processing Element. AKA Core. See ARM Glossary at
    http://infocenter.arm.com/help/topic/com.arm.doc.aeg0014g/ABCDEFGH.html

Fix
Use dap_ap_get_select() to get ap value.
a. Retrieve current ap value by calling dap_ap_get_select();
     src/flash/nor/kinetis.c
     src/target/arm_adi_v5.c

b. The code is correct (dap->ap_current >> 24), but it's better to use
   dap_ap_get_select() so everything could be synchronized.

Paul Fertser bdfd5bbe04 target/arm_adi_v5, cortex_m: retry ahbap_debugport_init few times in case of an error
Some targets need arbitrary amount of time (usually not too long)
after reset (both sysresetreq and srst) to do initialisation, and
SWD/JTAG is not available during that. According to PSoC4 docs, the
debugger should try connecting until it succeeds.

Also ahbap_debugport_init might be necessary to perform after using
hardware srst too, so add it there (except for the targets that
support srst_nogate since they are very unlikely to need it).

and OpenOCD would continue to try using dbgbase = 0, which happened to
work for e.g. AM437x.

This patch adds a clear indication to the user that to access such a
target, dbgbase must be set manually in the config.

The removed code is not needed now because target polling should lead

Paul Fertser b71ae9b1a7 target: fix timer callbacks processing
Warning, behaviour change: before this patch if a timer callback
returned an error, the other handlers in the list were not called.

This patch fixes two different issues with the way timer callbacks are
called:

1. The function is not designed to be reentrant but a nested call is
possible via: target_handle timer event -> poll -> target events
before/after reexaminantion -> script_command_run ->
target_call_timer_callbacks_now . This patch makes function a no-op
when called recursively;

2. The current code can deal with the case when calling a handler
leads to its removal but not when it leads to removal of the next
callback in the list. This patch defers actual removal to consolidate
it with the calling loop.

These bugs were exposed by Valgrind.

Paul Fertser dccbf7d88d armv7m: add FPU registers support
This patch adds the fpv4-sp-d16 registers to the armv7m register set.

The work is inspired by Mathias K but takes a different approach:
instead of having both double and single presicion registers in the
cache this patch works only with the doubles and counts on GDB to
split the data in halves whenever needed.

Tested with HLA only (on an STM32F334 disco board).

Currently this patch makes all ARMv7-M targets report an FPU-enabled
target description to GDB. It shouldn't harm if the user is not trying
to access non-existing FPU. However, the plan is to make this depend
on actual FPU presence later.

Christopher Head 0228f8e827 Cortex A: fix extra memory read and non-word sizes
Without this patch, to perform a memory read, OpenOCD first issues an
LDC instruction into DBGITR in Stall mode (thus executing the
instruction), then switches to Fast mode and reads from DBGDTRTX once
for each word to transfer.

At the very end of the transfer, the final Fast mode read of DBGDTRTX
has, as always, the side effect of re-issuing the LDC instruction. This
causes two problems:

(1) If the word immediately beyond the end of the requested region is
inaccessible, this spurious LDC will cause a fault. On a fast CPU, the
LDC will finish executing by the time the poll of DSCR takes place,
failing the entire memory read. On a slow CPU, the LDC might finish
executing later, leaving an unexpected and confusing sticky fault lying
around for the next operation to see.

(2) If the LDC succeeds, it will leave the loaded word in DBGDTRTX, thus
setting DBGDSCR.TXFULL=1. The cortex_a_read_apb_ab_memory routine
completes without consuming that last word, thus confusing the next
routine that tries to use DBGDTRTX (this may not have any visible effect
on some implementations, because writing to DBGDTRTXint when TXFULL=1 is
defined as Unpredictable, but I believe it caused a visible problem for
me).

With this patch, the bulk mem_ap_sel_read_buf_noincr is modified to omit
the last word of the block. The second-to-last read of DBGDTRTX by that
function will cause the issue of the LDC for the last word. After
switching back to Normal mode and waiting for that instruction to
finish, do a final read of DBGDTRTX to extract the last word into the
buffer, leaving TXFULL=0.

Without this patch, memory accesses are always expanded such that they
are aligned to the access size. With this patch, accesses are issued
exactly as ordered by the caller. The caller is expected to handle
fragments at the beginning and end of the transfer if the address is
unaligned and an unaligned access is not desired.

Without this patch, the DFAR and DFSR registers, which report the
location and status of data faults, are ignored while performing memory
accesses, which could cause problems debugging an OS page fault handler.
With this patch, DFAR and DFSR are preserved across memory accesses, and
DFSR is decoded in the event of a synchronous fault to provide the
caller with more information about the reason for failure.

Thanks to Boris Brezillon for the original patch whose ideas led to the
non-word access mechanism implemented here and to various code reviewers
for their comments.

Andreas Fritiofson 0ecb0396d4 nds32: Use the correct method to access registers
The registers are represented as bit arrays intended to be accessed using
the buf_set_* and buf_get_* functions. Storing the register values in
integers enables accessing them directly, which gives different results
depending on host byte order.

Convert the register store to use a byte array instead and fix all the
byte order bugs uncovered by that.

Also merge the 32 and 64 bit register fields. Only one of them is used at
a time and after the change to byte arrays their types are also the same.

Paul Fertser 355f4cadbb Use (uint8_t *) for buf_(set|get)_u(32|64) instead of (void *)
This helps to uncover incorrect usage when a pointer to uint32_t is
passed to those functions which leads to subtle bugs on BE systems.

The reason is that it's normally assumed that any uint32_t variable
holds its value in host byte order, but using but_set_u32 on it
silently does implicit pointer conversion to (void *) and the
assumption ends up broken without any indication.

In the case of xscale, the use of -variant is dubious since

1) it's used as a redundant irlen specifier,
2) it carries a comment that it doesn't really need it and
3) only two xscale configs even specify it.

Paul Fertser e77b7447f7 target/arm_dpm: prevent endless loop in arm_dpm_full_context()
The code treats registers that are shadowed in FIQ mode in a special
way: to read them out the target is first switches to USR mode. But
since USR != ANY the current implementation later skips register read,
and the loop becomes endless in case any !valid ARM_MODE_ANY is
present at the moment arm_dpm_full_context() is called. This was
reported in https://sourceforge.net/p/openocd/tickets/76/. The issue
surfaced because 2efb1f14f6 added two
ARM_MODE_ANY registers ("sp" and "lr") which were not normally read,
so at the time a user was calling "arm reg" they were not valid.

Fix this by changing the mode appropriately while keeping the "mode"
variable state intact so it would later match register's mode.

Compile-tested only.
