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.

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.

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

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.

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.

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 2efb1f14f611f2ff8a380b703f3e8bcb8a95d1ad 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.

stm32lx: refactor and add support for STM32L0xx

This adds initial support for the STM32L0 family, specifically the ID
code 417 variant. The 'L0 has 128B rather than 256B pages as well as a
different number of pages per sector. It also has several key registers
and register sets in different locations from the STM32L1xx parts.

This change therefore takes the opportunity to reorganize part information into
a const table (it was previously determined by a set of control statements) and
abstracts away some of the low-level details to make them generic for L1 and
L0 parts.

We also include the first bank's size (for dual bank parts) in the new
device information table (and correct that size for the 0x437 variant
which is 256 rather than 192KB).

The 'L0 parts will not use the built-in loader/helper for Flash writing.

jtag: usb_blaster: fix initialization regression

As Daniel pointed out, since the rewrite of the USB Blaster driver, the
initialization behaviour has change. The initial flush of the FIFOs is
not longer done with a specific USB setup packet, but with a write
filling up the blaster queues.

The problem is, quoting Daniel :

    When the CPLD is in bit banging mode (as is usually the case), the
    first 0x00 byte sets all pins to low and disables the output
    driver. Disabling the output drivers is a few nanoseconds slower
    than changing a pin from high to low, so I see a spike towards GND
    on my reset line when that byte is sent over USB. The spike is too
    short to have an effect on the board.

    When the 4096 0x00 bytes are processed and the TMS=1 is to be
    generated, all I see is several microseconds of low level on all
    pins, resetting my board.

This patch changes the way the initialization is done :
- at driver init, nothing is sent towards the usb-blaster
   This gives time for init script to setup PIN6 and PIN8 (resets)
- at the very first driver command, the initialization is done :
   - the output is in bit bigbang mode
   - the PIN6 and PIN8 are computed according to init script
   - the 4096 computed output is sent

stlink_usb: Fix swallowed error on read/write operations, add retries on SWD WAIT, clean up error debug output.

- stlink_usb_get_rw_status() had a bug where FAULT or WAIT responses
  in read/write operations were ignored, leading to incomplete data.

- Added wrapper stlink_cmd_allow_retry to handle
  SWD_AP_WAIT/SWD_DP_WAIT statuses in most commands. These statuses
  appear if an SWD read or write received a WAIT ACK response from the
  target more than 4 times in a row. The driver retries the operation
  (with exponential backoff) before failing outright (in testing 1
  retry was always enough.)

- As part of the implementation of stlink_cmd_allow_retry a large
  number of lines of boilerplate were refactored.

- Fleshed out stlink_usb_error_check and added it to some more code
  paths so WAIT or FAULT responses are logged to debug. WAIT responses
  will be logged even if they are subsequently retried, which should
  help in case the retries have subtle side effects (none
  anticipated.)

Tested with two targets: STLINK F0 Discovery, Nordic NRF51822. Only
tested with STLINK V2 programmers.

This is intended to fix cmsis_dap_vid_pid command but it doesn't
because cmsis-dap has only one transport and it's auto-selected from
"interface" command handler (before any other commands are run) and as
the result cmsis_dap_usb_open() is called too early.

Openocd: svf: Add ability to ignore svf_check_tdo errors

Added Openocd commandline argument to ignore_error when the
read back TDO does not match to expected value specified with
TDO after masking with what is specified in MASK. This allows
to continue to play entire SVF file ignoring errors.
Error logs clearly show the failure reason and prints
read back TDO value.

Add FTDI SWD driver

This is usable on most or all FTDI adapters using a small hardware tweak.

TCK goes to SWCLK as expected. TDO should be wired to SWDIO. For TDI there
are two options:

Either add a 74HC126 or similar tri-state buffer between TDI and SWDIO,
with OE controlled by a signal named SWDIO_OE. Or simply connect TDI and
SWDIO together via a suitable resistor (220-470 ohms or so depending on
the drive capability of the target and adapter).

nSRST (and of course Vcc, GND) may be connected too but all other signals
should be NC.
