Antonio Borneo 25218e8935 jtag: remove minidriver code and minidriver-dummy
With zy1000 removed, there is no other implementation that uses
the minidriver, apart from the test/example minidriver-dummy.
While the idea of the minidriver is probably still valid (that is
to intercept jtag primitives before serialization), there is no
current use case, no guarantee it is really working, and the way
it was implemented (by macros and #if conditionals) is really hard
to maintain and test.

Let's let it rip in git history, from where it could eventually be
taken back in a more modern implementation.
The entry points of minidriver API are still in the code with the
original names.

Antonio Borneo 6a81bad3b9 configure: split build of hla layouts
Current hla driver supports two "layout": stlink and ti-icdi.
The configure script allows to independently enable/disable the
the two layout. But in reality by selecting only one of them the
whole hla driver is built, including both "layouts".
This is currently not a big issue because the dependencies of the
two layout are the same (libusb), so we are sure that selecting
one of them would permit to build both.
This is going to change with the merge of a third "layout" for
Nuvoton Nu-Link, because it would be based on hidapi.
We need, at least, to decouple the build of libusb and hidapi
"layouts". A full decouple of each "layout" is also welcome to
match the selection done during configure.

Introduce a new automake macro for each of the two "layout" and
use them to conditionally build the "layout" files.
Use the existing autoconf macros to conditionally compile the code
that depends by the "layout".

Apply to the driver the required changes as in [2].
While there, remove the duplicated struct xlnx_pcie_xvc_transports

Antonio Borneo 944d3e6771 stlink: add DAP direct driver
STLINK-V3 and the new firmware V2J24 for ST-LINK/V2 provide API
to directly access the DAP registers.
This mode permits to use the native target in cortex_m.c, with no
need to override it with the target in hla_target.c.
Other advantages wrt HLA are: support for Cortex-A cores, support
for SoC multi-core and/or multi AP, support for OpenOCD commands
"dap" thus including control of CSW.
This obsoletes the existing HLA driver for ST-Link, that should
anyway be kept for those cases where it's not possible to update
the ST-Link firmware.

This commit introduces the minimal implementation for direct DAP
access. The implementation is much slower than the HLA because
every memory transfer requires several USB packets. Further
commits will close the performance gap.
The whole ST-Link driver is compiled under BUILD_HLADAPTER, to
remove the need to split the driver between the two modes. This
has to be reworked, but it's quite invasive!
A new interface file stlink-dap.cfg is added and should be used
in place of stlink.cfg to enable the DAP mode.
Documentation is updated and reports limitation on the maximum AP
number that can be accessed by ST-Link for some firmware already
tested.

keeping in two separate struct the specific API jtag_ops and
swd_ops.
Move the allocation of *adapter_driver from the JTAG-specific
file core.c to the more adapter-specific file adapter.c
While splitting the old jtag_interface for every driver, put
the fields in the same order as in the struct declaration so
we keep a consistent code across all the drivers.

While other transport specific API could/would be added as
separate ops, nothing is done here for HLA.

Franck Jullien 87e91f4db9 jtag/drivers: add USB-Blaster II
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.

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.

Andreas Fritiofson f5e97b5e1b Add FTDI JTAG driver using MPSSE layer
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).

Jan Dakinevich 34d1f82c75 jtag: basic support for P&E Micro OSBDM (aka OSJTAG) adapter
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.
