This patchs adds a new access driver for the existing
USB-Blaster interface driver.
This interface (as it is build-in on the sockit development
board) is composed of a Cypress EZ-USB plus a CPLD.
The Cypress chip as an embedded 8051 microcontroller.
When it's powered up, the firmware is downloaded to the
chip then the device is disconnected and reconnected with
the new firmware.
The USB-Blaster II protocol is almost identicial to
the old one. The only difference is that you need to
send a 0x5F before read TDO back. This command
seems to copy TDO buffer datas to the endpoint buffer.
Driver will be auto enabled if libusb-1.0 is detected.

This is based on work from:
https://github.com/TheShed/OpenOCD-CMSIS-DAP/tree/cmsis-dap
Main changes include moving over to using HIDAPI rather than libusb-1.0
and cleaning up to merge into master. Support for reset using srst has
also been added.
It has been tested on all the mbed boards as well as the Freedom board
from Freescale. These boards only implement SWD mode, however JTAG mode
has been tested with a Keil ULINK2 and a stm32 target - but requires a lot
more work.

This patch adds a driver for the jtag_vpi server [1]. This server is
now part of the ORPSoC version 3 (OpenRISC Reference Platform SoC).
The jtag_vpi server provides an interface between OpenOCD and a simulated
core.

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.

Andes AICE uses USB to transfer packets between OpenOCD and AICE.
It uses high-level USB commands to control targets instead of using
JTAG signals. I define an interface as aice_port_api_s. It contains
all basic operations needed by target-dependent code.

This driver implements a bitbang jtag interface using gpio lines exported via
sysfs.
The aim of this driver implementation is to use system GPIOs but to avoid the
need for an additional kernel driver.
A config suitable for RaspberryPi is included.

Based on ft2232.c but uses the MPSSE layer for low-level access, greatly
simplifying the JTAG logic. Remove all libftdi/FTD2XX code and all layout
specific code. Layout specifications are instead handled in Tcl.
Use a signal abstraction to enable Tcl configuration files to define
outputs for one or several FTDI GPIO. These outputs can then be
controlled using the ftdi_set_signal command. Special signal names are
reserved for nTRST, nSRST and LED (for blink) so that they, if defined,
will be used for their customary purpose.
Depending on the type of buffer attached to the FTDI GPIO, the outputs
have to be controlled differently. In order to support tristateable
signals such as nSRST, both a data GPIO and an output-enable GPIO can be
specified for each signal. The following output buffer configurations are
supported:
* Push-pull with one FTDI output as (non-)inverted data line
* Open drain with one FTDI output as (non-)inverted output-enable
* Tristate with one FTDI output as (non-)inverted data line and another
FTDI output as (non-)inverted output-enable
* Unbuffered, using the FTDI GPIO as a tristate output directly by
switching data and direction as necessary
The data and output-enables are specified as 16-bit bitmasks,
corresponding to the concatenation of the high and low FTDI GPIO
registers. To specify an unbuffered output, use the same bitmask
for both data and output-enable.
The adapter configuration file must also specify default values for the
FTDI data and direction GPIO registers, and the channel being used (if
different from 0).

This driver provides support for the P&E Micro OSBDM adapter (sometimes
named as OSJTAG), mounted on the Freescale TWRK60N512 bord. Thus, it
provides a quick start when working with this board. The driver doesn't
use BDM commands, but work with OSBDM adapter using only JTAG commands.

The driver sends ascii encoded bitbang commands over unix sockets or TCP to
another process. This driver is useful for debugging software running on
processors which are being simulated.
This includes a driver and matching config file. This support needs to be
enabled through the initial "configure" (use "--enable-buspirate").
