442f1540d5 Improve J-Link driver and introduce libjaylink.
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.

2bb9256c34 jtag: commands: save a pointer to list tail
By saving a pointer to the tail of the list,
we don't need to traverse the entire command
queue before we're able to append an item to
it.

With this patch, I see a 10% improvement when
using the embedded XDS100v2 on AM437x IDK board
to load a 4MiB binary (linux zImage) to DDR
with load_image.

IOW, we went from ~305kB/sec to ~336kb/sec.

72c3464be4 jtag: cmsis-dap: Issue disconnect before reconnecting
cmsis-dap protocol has both DAP_Connect and DAP_Disconnect commands.
Logically if cmsis_dap_swd_switch_seq() calls DAP_Connect in connected
state it should call DAP_Disconnect first.

Doing so surprisingly solves problems on Atmel EDBG with target SAMD/R/L/C.
Without this change SWD communication breaks after reset run/halt
in config "reset_config srst_only" and reconnect trials repeatedly
fail with "SWD ack not OK: 0 JUNK"

daf9bcf77f startup: Fixed measure_clk to return kHz instead of MHz.
The original code had iterated 10,000,000 times and taken the elapsed 
time divided by 10,000, to yield kHz which is mathematically correct 
only if we were measuring time in seconds, but we are measuring time in 
 milliseconds, so the correct divisor is actually 10,000,000.  Previous 
code would report 0.500 for actual measured speed of 500 kHz.

355f4cadbb Use (uint8_t *) for buf_(set|get)_u(32|64) instead of (void *)
This helps to uncover incorrect usage when a pointer to uint32_t is
passed to those functions which leads to subtle bugs on BE systems.

The reason is that it's normally assumed that any uint32_t variable
holds its value in host byte order, but using but_set_u32 on it
silently does implicit pointer conversion to (void *) and the
assumption ends up broken without any indication.

fe04314c2a jtag/drivers/cmsis-dap-usb: fix cmsis_dap_serial
Previously the serial wasn't actually used in hid_open() call,
which meant that the first device with matching vid:pid was opened
irrespective of the actual serial number.

145f8ed817 stlink: add reconfigurable speed support
The ability to change the speed has been added to firmware versions J22 and
above. Any attempt to change on earlier versions will be ignored without error,
as the existing code does.

For supported firmware versions the driver will attempt to get as close as
possible to supported speeds (never higher).

The default stlink speed on power up is 1.8MHz.
The driver will now also print supported clocl speeds during init.

9f6d4d1302 swd: handle various failure conditions
When communication with target fails for whatever reason, it makes
sense to do JTAG-to-SWD (in case the target got power-cycled or the
DAP method was reset anyhow), SWD line reset sequence (part of
JTAG-to-SWD already) and the mandatory IDCODE read. Schedule that to
be performed on the next poll.

Fix the return values for ftdi and jlink drivers to be consistent with
OpenOCD error codes and remove ad-hoc calls to perform DAP method
switching (as it's now done from the upper layer automatically).

487c57d9a2 libusb: introduce jtag_libusb_choose_interface() and use it for JLink
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.

being "debug unlock" that fully mass-erases the device and unprotects

Change 2288 fixed the extraneous reset caused by set_configuration that
crashed the LPC Link-2 running JLink firmware and works on windows platforms.
On Linux however, conditional code was still calling USB reset and caused
the adapter to crash on any non-windows platforms.
