Antony Pavlov c5d8988316 checkpatch.pl: check for openocd tree, not for kernel tree
checkpatch.pl looks for linux kernel specific paths and files
to check source tree. As openocd misses kernel files it ends
with this error message:

    Must be run from the top-level dir. of a kernel tree

This patch also renames 'kernel' -> 'openocd'
in source tree-related messages.

Due to checkpatch checking modifications on itself, lift the
restriction on having no spaces at the start of a line for Perl
scripts. This can be readded back later.

Anders 1662c854e2 flash/nor/lpcspifi.c: fix bug that prevented clean reset after flash write
After SPI flash was written by the assembly language stub,
the last SPI command was not terminated by raising CS.
This left the SPI device in a hung state that prevented the
flash from being read by the M4 SPIFI controller, even after
the M4 was fully reset. To access the flash via SPIFI, it was
necessary to completely power cycle the board.

This fix adds the missing instructions to raise CS and
terminate the SPI command after the last byte. This allows
the M4 to be resumed or reset cleanly after flashing. The
SPIFI memory is now immediately accessable at address
0x1400 0000 after flashing is complete.

Jim Paris f30bb58644 nrf51: fix UICR erase
nrf51_erase_page() checks for (sector->offset == NRF51_UICR_BASE) to
determine if the UICR should be erased.  However, sector->offset for
the UICR bank is set to 0 in nrf51_probe, so this code is never hit.
Attempting to erase UICR ends up erasing the first flash sector.

Use bank->base instead to determine if UICR is being erased.

This introduces a new common function that allows auto-discovery of a
suitable USB interface based on class, subclass and protocol
matching. It claims the interface and returns the corresponding
endpoints number to the caller.

The need for this arised due to nRF51822 USB dongle which comes with
an "on-board Segger J-link debugger" having 3 interfaces, so the
current code can't work at all with it (in this particular case the
last interface needs to be choosen). This also removes special
handling of JLink-OB endpoint numbers as it's now possible to
autodetect them as well as the standard JLink endpoints.

Andrey Yurovsky db4b2c2536 at91samd: fix protect, add EEPROM and boot commands
There were two problems with the _protect() feature:
1. The address written was off by a factor of two because the address
register takes 16-bit rather than 8-bit addresses.  As a result the
wrong sectors were (un)protected with the protect command.  This has
been fixed.
2. The protection settings issued via the lock or unlock region commands
don't persist after reset.  Making them persist requires modifying the
LOCK bits in the User Row using the infrastructure described below.

The Atmel SAMD2x MCUs provide a User Row (the size of which is one
page).  This contains a few settings that users may wish to modify from
the debugger, especially during production.  This change adds commands
to inspect and set:
- EEPROM size, the size in bytes of the emulated EEPROM region of the
  Flash.
- Bootloader size, the size in bytes of the protected "boot" section of
  the Flash.

This is done by a careful read-modify-write of the special User Row
page, avoiding erasing when possible and disallowing the changing of
documented reserved bits.  The Atmel SAMD20 datasheet was used for bit
positions and descriptions, size tables, etc. and testing was done on a
SAMD20 Xplained Pro board.

It's technically possible to store arbitrary user data (ex: serial
numbers, MAC addresses, etc) in the remaining portion of the User Row
page (that is, beyond the first 64 bits of it).  The infrastructure used
by the eeprom and bootloader commands can be used to access this as
well, and this seems safer than exposing the User Row as a normal Flash
sector that openocd understands due to the delicate nature of some of
the data stored there.

Andrey Yurovsky 592d0d514d at91samd: add erase/secure commands, minor fix
Reference code for the SAMD2x disables caching in the NVM controller when
issuing NVM commands.  Let's do this as well to be consistent and safer.

Add a "chip-erase" for the Atmel SAMD targets that issues a complete Chip Erase
via the Device Service Unit (DSU).  This can be used to "unlock" or otherwise
unbrick a chip that can't be halted or inspected, allowing the user to reflash
with new firmware.

Add a "set-security" command which issues an SSB.  Once that's done and the
device is power-cycled, the flash cannot be written to until a "chip-erase" is
issued.  The chip-erase cannot be issued by openocd at this time because
the device will not respond to a request for the DAP IDCODE.

Paul Fertser ec9ccaa288 arm_adi_v5: make dap_lookup_cs_component() traverse subtables and handle multicore
When looking for a debug base address of a core, one should search
through all the ROM tables, not just the top-level one.

This code also assumes that the first found entry (in a depth-first
search) will correspond to core 0, the second to core 1 etc.

The patch is supposed to be an alternative implementation of

When GDB requests a breakpoint on a 32bit Thumb-2 instruction it
sends a length of 3 which the current code rejects. Using the
existing two byte breakpoint for this case appears to work fine.

The use of length==3 for this case is mentioned in a few places:

Andreas Fritiofson c0b8e605f7 command: Fix confusing syntax error message
If the user executes a command with an invalid subcommand, the error
message is extremely unhelpful:

> flash write test.elf
flash write test.elf: command requires more arguments

This is because any command line that starts with a valid command group is
classified as a group, triggering ocd_bouncer to print the confusing
message.

Fix by requiring that to be a command group, the command line must not
contain any unknown tokens after the last valid (sub-)command group. That
is OK because command groups don't have handlers defined and thus can't
take any parameters.

Also fix the error message for "unknown" type to be similar to the error
message that is printed (by Jim) for non-existent primary commands.

Andreas Fritiofson 1c021ed0af target: Remove "-variant" argument
Remove this underutilized feature. Despite the fact that a lot of configs
specifies a arbitrary "variant", only the xscale target actually defines
any.

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.

If there's a future target that needs a variant set, a target specific
option could be added when needed.
