Matthias Welwarsky 8704e53665 armv7a: fix handling of inner caches
ARMv7 architecture allows up to 7 cache levels that are architecturally
visible, as opposed to "system caches", which are outside of the domain
defined by ARMv7 and require separate management. This patch enables
detection and identification of caches at all levels. It also implements
a new "flush-all" function that cleans & invalidates all cache levels to
the "Point of Coherence".

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.

Marc Schink 442f1540d5 Improve J-Link driver and introduce libjaylink.
This patch uses libjaylink which is a library to access J-Link
devices. As other tools which are not in the scope of OpenOCD also
need to access J-Link devices a library is used. A firmware upgrade
tool and an advanced configuration tool for J-Link devices are under
development.

Further versions of libjaylink will support additional features
OpenOCD could benefit from. This includes TCP/IP as additional
possibility to connect to J-Link devices as well as power tracing and
device internal communication. The latter is used to access
peripherals on some development boards (e.g EFM32 STK and DVK).

Integration of libjaylink is realized with a git submodule like
jimtcl. As libjaylink depends on libusb-1.0 only, no additional
dependency is introduced for OpenOCD.

All low-level JTAG and SWD implementations of the current driver are
left untouched and therefore no incompabilities are to be expected.

Improvements of this patch:

 * Support for more USB Product IDs, including those with the new
   scheme (0x10xx). The corresponding udev rules are also updated.
 * Device selection with serial number and USB address.
 * Adaptive clocking is now correctly implemented and only usable for
   devices with the corresponding capability.
 * The target power supply can now be switched without the need for
   changing configuration and power cycling the device.
 * Device configuration is more restrictive and only allowed if the
   required capabilities are available.
 * Device configuration now shows the changes between the current
   configuration of the device and the values that will be applied.
 * Device configuration is verified after it is written to the device
   exactly as the vendor software does.
 * Connection registration is now handled properly and checks if the
   maximum number of connections on a device is reached. This is also
   necessary for devices which are attached via USB to OpenOCD as
   some device models also support connections on TCP/IP.
 * Serial Wire Output (SWO) can now be captured. This feature is not
   documented by SEGGER however it is completely supported by
   libjaylink.

This patch and libjaylink were tested on Ubuntu 14.04 (i386),
Debian 7 (amd64), FreeBSD 10.0 (amd64) and Windows XP SP3 (32-bit)
with the following device and target configurations:

 * JTAG: J-Link v8.0, v9.0 and v9.3 with AT91SAM7S256
 * SWD: SiLabs EFM32 STK 3700 (EFM32GG990F1024)
 * SWD: J-Link v8.0, v9.0 and v9.3 with EFM32GG990F1024
 * SWD: XMC 2Go (XMC1100)
 * SWD: XMC1100 Boot Kit (XMC1100)
 * SWD: IAR Systems / Olimex Eval Board (LPC1343F)
 * SWD: Nordic Semiconductor nRF51 Dongle (nRF51422)
 * SWD: SiLabs EZR32 WSTK 6220A (EZR32WG330FG60G)

Except for Windows XP all builds are tested with Clang in addition to
GCC. This patch and libjaylink are not tested on OSX yet.

Jakub Kubiak 9a6d6b51b7 flash/nor/lpc2000: add alternative part ID for LPC1343
http://support.code-red-tech.com/CodeRedWiki/DebugAccessChip
> Note that once you have recovered debug access to your MCU, then in most cases you should then modify your Debug Configuration to turn vector catch off again. If this is not done, then this can cause problems in some circumstances with some versions of the Code Red IDE. For example with NXP LPC13xx parts, connecting more than once to the MCU with vector catch enabled can lead to the part ID being incorrectly read - which can again cause debug connections to fail
This patch adds an alternative part ID for LPC1343. With this patch "program" command works fine for flashing.

Tomas Vanek 26a65f4f13 flash: at91samd: flash write code cleaning
SAMD driver suffered from following problems:

1) Flash was erased as an integral part of flash write.
It was not documented so with usual workflow it resulted
in erasing flash twice (and reducing flash lifespan)
and in almost double flashing time.

2) Sector erase was silently skipped if "is_erased" flag was set.
"is_erased" logic was not reliable, e.g. when a row write
was aborted after successful write of some pages, sector was
still considered as erased. "is_erased" flag could not
cope with flash writes from a user program.

3) Writing of a block with start address unaligned to a flash page
resulted in failed assert and OpenOCD abort.

4) Disabling cache in bit 18 of 16-bit halfword never worked.
MCU implements cache invalidate in hardware so there is no need
to take care about. This bug was reported by Tony DiCola.

New code does not erase flash in write operation.
Instead it traditionally relies on erasing flash beforehand.
"is_erased" logic and cache disabling is completely removed.
It simplifies write procedure a lot and flash write is now faster.

The change partly solves ticket #109 SAMD/SAM4L driver doubles flash erase.

There is minimal change between the two variants, but in

With this patch the write row function will now issue a page write
command after each of the four pages in the row if the MANW (manual
write) bit is set. This also fixes flash write for the SAMC20/SAMC21
devices which have the MANW bit set by default as well.

I have also moved the device ID (DID) register bitfield extraction
from the find_part into helper macros. These can be used in the future
if there are more workarounds for specific devices.

Tomas Vanek 751e2454bf at91samd: handle reset run/halt in DSU
Atmel introduced a "Device Service Unit" (DSU) that holds the CPU
in reset if TCK is low when srst (RESET_N) is deasserted.
Function is similar to SMAP in ATSAM4L, see http://openocd.zylin.com/2604

Atmel's EDBG adapter handles DSU reset correctly without this change.

An ordinary SWD adapter leaves TCK in its default state, low.
So without this change any use of sysresetreq or srst
locks the chip in reset state until power is cycled.

A new function dsu_reset_deassert is called as reset-deassert-post event handler.
It optionally prepares reset vector catch and DSU reset is released then.

Additionally SWD clock comment is fixed in at91samdXX.cfg and clock is
lowered a bit to ensure a margin for RC oscillator frequency deviation.
adapter_nsrst_delay 100 is commented out because is no more necessary after

16000kHz is only safe after PLLs have been locked
properly. Until that's done (with reset init), we
can only safely run at 1000kHz.

According to Infineon, XMC4500 EES AA13 with date codes before GE212 -
as seen on an XMC4500 General App Kit - had a zero SCU_IDCHIP register.

Handle this by extending our checks to not error out on zero SCU_IDCHIP
and by printing a useful info string in that case.

Jeff Ciesielski 33b048d456 flash: New driver for XMC4xxx microcontroller family
This is a complete flash driver for the Infineon XMC4xxx family of
microcontrollers, based on the TMS570 driver by Andrey Yurovsky.
The driver attempts to discover the particular variant of MCU via a
combination of the SCU register (to determine if this is indeed an
XMC4xxx part) and the FLASH0_ID register (to determine the variant).
If this fails, the driver will not load.
The driver has been added to the README and documentation.

Tests:
* Hardware: XMC4500 (XMC4500_relax), XMC4200 (XMC4200 enterprise)
* SWD + JTAG
* Binary: 144k, 1M

Note:
* Flash protect only partly tested. These parts only allow the flash
  protection registers (UCB) to be written 4 times total, and my devkits
  have run out of uses (more on the way)

Future Work:
* User 1/2(permalock) locking support via custom command
* In-memory flash loader bootstrap (flashing is rather slow...)

Matthias Welwarsky 411ca773f0 armv7a: re-read ttb information if ttbcr changes
If ttbcr is changed after the debugger has examined a target for the
first time, address translations may fail. This problem does not show up
with Linux because it doesn't use ttbr1, but it shows with other OS that
use this feature. If the debugger connects to the target while it's in
u-boot, all address translations will fail after the OS has booted and
the target can not be debugged.

This patch reads the ttbcr in armv7a_mmu_translate_va() and compares it
a cached value. If a difference is detected, armv7a_read_ttbcr() is called
to re-parse the ttb configuration and update the cache.
