Due to signal propagation delays, sampling TDO on rising TCK can become
quite peculiar at fast TCK rates. However, FTDI chips offer a possiblity
to sample TDO on falling edge. With this change, stable operation can be
achieved at 30MHz clock even over 10cm ribbon cable.

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 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

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...)

Many FPGA board speak JTAG and have a SPI flash for their bitstream
attached to them. The SPI flash is programmed by first uploading a
proxy bitstream to the FPGA that connects the JTAG interface to the
SPI interface if the IR contains a certain USER instruction. Then the
SPI flash can be erase, written, read directly through the JTAG DR.
The JTAG and SPI signaling is compatible. Such a proxy bitstream only
needs to connect TDO-MISO, TDI-MOSI, TCK-CLK, and the activate the
chip select when the IR contains the special instruction and the JTAG
state machine is in the DR-SHIFT state.

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.
