To alleviate the need to bitbang SWD, I've written a SWD SPI
implementation. This code is inspired by the work of luppy@appkaki.com
as shown at github.com/lupyuen/openocd-spi but with the desire to be
more generic. This implementation makes use of the more common 4 wire
SPI port using full duplex transfers to be able to capture the SWD ACK
bits when a SWD TX operation is in progress.
TEST:
Connects successfully with the following combinations:
Hosts:
Raspberry Pi 4B
Unnamed Qualcomm SoC with QUPv3 based SPI port
Targets:
Raspberry Pi 2040
Nordic nRF52840
NXP RT500

Previously, Linux assigned gpiochip numbers sequentially depending on
when the chip driver was probed. As RP1 is on the end of a PCIe link, it
is probed later than the on-board chips (including expanders connected
over SPI/I2C). This meant that RP1's gpiochip assignment was at an
offset that could potentially change.
A downstream kernel patch now assigns fixed offsets for RP1 and the
onboard gpiochips. Query the device tree to get proper GPIO_CHIP index.

The STLink API that supports dap-direct is available from STLink
firmware v2j24, published in early 2015.
We can reasonably expect that any old STLink still in use today
has got at least one firmware update during the last 10 years.
Most of the board files in upstream OpenOCD still use the STLink
in HLA mode. This limits the test coverage of the dap-direct code,
which was introduced in OpenOCD v0.11.0.
- Rename interface/stlink.cfg as interface/stlink-hla.cfg to still
provide support for HLA, adding a deprecated message.
- Rename interface/stlink-dap.cfg as interface/stlink.cfg to make
dap-direct the default trasport.
- Add a redirect file interface/stlink-dap.cfg for users that have
out-of-tree custom board files.
- Update all the board files to the new setup.
- Remove STLink HLA mentions from the documentation, while adding
a reference to interface/stlink-hla.cfg

This is the driver code for NanoXplore's ANGIE USB-JTAG Adapter.
The driver is based on the openULINK project.
This driver communicate with ANGIE's firmware in order to establish
JTAG protocol to debug the target chip.
Since the ANGIE Adapter has a Spartan-6 FPGA in addition to the
FX2 microcontroller, the driver adds two functions, one to download
the firmware (embedded C) to the FX2, and the second to program
the FPGA with its bitstream.
Add ANGIE's configuration file to tcl/interface/
Add the device VID/PID to 60-openocd.rules file.

The old configuration files did not work because of a missing
'at91sam9260minimal.cfg' file. Also, the config files were placed
wrongly. Update them, put them to the proper location, merge the two
supported boards into one, remove now superfluous include, remove
defunct web page, etc.. Tested with a Calao USB-A9G20 and a hacked
'device_desc' to match. Native support for it will come next.

Speed calibration coeffs are computed from cpufreq/scaling_max_freq
and from the device-tree compatibility information.
Raspberry Pi linux offers /dev/gpiomem for non-root access
to the GPIO registers since ~2016.
Do not configure 'bcm2835gpio peripheral_base' as it is necessary
only if /dev/mem is used - it requires running OpenOCD as root
- it's a security risk so it should be avoided.
The configuration of the GPIO connector (40-pin header)
is factored out and ready to use in interface configuration
for other driver (e.g. linux gpiod).
Mark raspberrypi2-native.cfg as deprecated and redirect
it to raspberrypi-native.cfg

The target nds32 and its companion adapter aice have not received
any real improvement since 2013.
It has been hard to keep them aligned during the evolution of
OpenOCD code, with no way for maintainers to really check if they
are still working.
No real documentation is present for them in OpenOCD.
The nds32 code triggers ~50 errors/warnings with scan-build.
The arch nds32 has been dropped from Linux kernel v5.18-rc1.
For all the reasons above, this code has been deprecated with
commit 2e5df83de7 ("nds32: deprecate it, together with aice
adapter driver") and tagged to be dropped before v0.13.0.
Let it r.i.p. in OpenOCD git history.
While there, drop from checkpatch list the camelcase symbols that
where only used in this code.
