Initial release of Ambiq Micro Apollo flash driver
supporting our sub-threshold (low power) Cortex M4F part,
and Evaluation Kit.
We have been shipping openocd to our customers for about one year.
The EVK boards are SWD only using ftdi. We also use two of the
other COM instances to display debug information.
It takes about 15 seconds to flash 512K, and mass erase is
about 5 seconds.
Tested by internal verification group, FAE's, and customer sites.
Merged commit 'refs/changes/17/3417/1' as suggested. Makefile.am
and drivers.c follow the new format to avoid conflicts.
Removed unused fault_capture command.
Added documentation for flash driver.

The capability to lock the debug interface on EFM32
controllers was lacking in OpenOCD.
After receiving some pointers by zapb_ and PaulFertser
on IRC (thanks guys!) I have added this capability.
This works by writing the required bits in the debug
lock word to '0'.
Note: there is currently no way to re-enable the debug
interface from OpenOCD as doing this requires specific
pin wiggling that is currently not implemented yet.
However: having the capability to lock the debug interface
is useful when building a volume programming jig.
You can flash the program code, verify and then
lock the debug interface so that the device cannot
be read when it is deployed in the field.

serial number _may_ be unique (and maybe not with embedded adapters) but

The Spansion FM4 family of microcontrollers does not offer a way to
identify the chip model nor the flash size, except for Dual Flash vs.
regular layout. Therefore the family is passed as argument and
wildcard-matched - MB9BFx6x and S6E2CC families are supported.
Iterations showed that ...
1) Just doing the flash command sequence from SRAM loader code for each
half-word took 20 minutes for an 8 KB block.
2) Doing the busy-wait in the loader merely reduced the time to 19 minutes.
3) Significant performance gains were achieved by looping in loader code
rather than in OpenOCD and by maximizing the batch size across sectors,
getting us down to ~2 seconds for 8 KB and ~2.5 minutes for 1.1 MB.
(Tested with SK-FM4-176L-S6E2CC-ETH v11, CMSIS-DAP v23.)

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.

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

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)

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

The JTAG and SPI signaling is compatible. Such a proxy bitstream only

This patch might influence openocd Tcl commands behaviour in subtle
ways, please give it a nice testing.
The idea is that if an OpenOCD Tcl command returns an error, an
exception is raised, and then the return code is propogated all the
way up (or to the "catch" if present). This allows to detect
"shutdown" which is not actually an error but has to raise an
exception to stop execution of the commands that follow it in the
script.
openocd_thread special-cases shutdown because it should then terminate
OpenOCD with a success error code, unless shutdown was called with an
optional "error" argument which means terminate with a non-zero exit
code.
