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.

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.

Paul Fertser 207237b920 tcl: introduce init_target_events and use it for gdb flashing events
This introduces a new global Tcl procedure that is run just after
init_targets and before init_boards.

Its default behaviour is to assign gdb-flash-erase-start and
gdb-flash-write-end to reasonable defaults.

The rationale for doing "reset init" before gdb erases and flashes
memory is that all flash drivers are written in assumption that they
can safely be used only after chip reset (plus chip-specific
configuration in the init handler if any). The need to use "reset
halt" after flashing is because a user expects running firmware after
loading to be the same as running it from power-on-reset.

James G. Smith 0ebf1eb94d hla/stlink: Re-order trace parameters to allow trace output file to be optional
Re-order the "trace" parameters to allow the raw capture (log) file to
be an optional feature. The clock frequency for calculating the "Async
Clock Prescalar" is always required when enabling trace processing and
is now the first "required" parameter.

The ST-Link driver is updated to use the (required parameter)
"trace_source_hz" non-zero value as the indicator of trace being
required, rather than the now optional output file descriptor being
non-NULL.

Background: This patch is groundwork for extending the OpenOCD SWO
capture to implement other (OpenOCD built-in) ITM/DWT processing where
the core trace support is required, but there is no requirement to
store raw trace data to a configured host file. By itself this patch
is almost a functional NOP, since without the other processing in
place there is no reason NOT to specify a capture file.

Andrey Yurovsky d998ea40f3 stlink: add SWO tracing support
Enable reading the SWO trace output via STLinkv2 dongles that support
it.

This adds an optional initialization parameter "trace" with which the user
specifies a destination file where SWO trace output is appended as it comes in
as well as the trace module's source clock rate.

STLink will be configured for a 2MHz SWO data rate (STLink's highest
supported rate) if the source clock is > 2MHz, otherwise the source
clock is used as the data rate directly.

For example:

trace swo.log 168000000

If "trace" is specified with a usable file path, the stlink_usb driver will
attempt to configure and read SWO trace data as follows:
- on _run(), the target's TPI and TMI are configured and the STLinkv2 is told
  to enable tracing.  Only generic ARM TPI and TMI registers are
  configured, any MCU-specific settings (ex: pin routing) are the
  responsibility of the target firmware.  The configuration applied is
  based on the STLinkv2's capabilities (UART emulation).
- on _v2_get_status(), the trace data (if any) is fetched from the
  STLink after the target status is checked and the target is found to
  be running.
- on _halt(), the STLink is told to disable tracing.

When fetching trace data, the entire trace frame is written to the output file
and that data is flushed.  An external tool may be used to parse the
trace data into a more human-readable format.

Tested on ARM Cortex M4F and M3 MCUs (STM32F407 and STM32L152).

Paul Fertser 962b3eb40c Add BCM2835 (as found in Raspberry Pi) interface driver
This adds support for JTAG programming by bitbanging GPIOs exposed on
the RaspberryPi's expansion header.

Tested by connecting directly to an STM32VLDiscovery board, without any
additional circuity. I observed maximum about 4MHz on the TCK pin with an
old analogue 'scope and about 100kHz when setting the speed to 100kHz.
Busyloop waiting is needed because even with a single 0ns nanosleep call
(with FIFO priority) it lowers the TCK speed to ~30kHz which is way too low
to be useful.

The speed testing with adapter_khz 2000 gave the following results:
sudo chrt -f 1 nice -n -19 ./src/openocd \
     -f interface/raspberrypi-native.cfg \
     -c "set WORKAREASIZE 0x2000" \
     -f target/stm32f1x.cfg -c "adapter_khz 2000"

wrote 131072 bytes from file random.bin in 3.973677s (32.212 KiB/s)
dumped 131072 bytes in 1.445699s (88.538 KiB/s)

This is 3.7 times faster for writing and 14.3 times faster for reading
compared to the generic sysfsgpio driver; probably the writing speed is
limited by the target itself here and reading speed might be considerably
higher too with appropriate connection and a capable target.

BCM2835 name is choosen over BCM2708 because the published peripherals
datasheet uses the particular model name and not family name.
