Tomas Vanek 5c46a5de49 jtag/drivers/bcm2835gpio: add peripheral_mem_dev config command
The bcm2835gpio driver preferred /dev/gpiomem for access to
memory mapped GPIO control and used /dev/mem as a fallback
only if it couldn't open /dev/gpiomem.

/dev/mem usually requires elevated rights or specific capabilities
of the opening process, so the fallback failed anyway.

Although /dev/gpiomem is the strongly preferred option with respect
to security, there could be also use cases which require /dev/mem
even if /dev/gpiomem is available (e.g. changing the GPIO pad
settings is necessary or testing/debugging OpenOCD).
It was difficult to handle such cases because they required
to block globally the system device /dev/gpiomem
(remove, rename or chmod).

Drop the fallback feature and select the memory device
by 'bcm2835gpio peripheral_mem_dev' configuration command.
Use /dev/gpiomem as a default.

Move the declaration outside the inline function so it get visible
by interface.c, which already includes interface.h

transaction count when assembling the packet. Fix it by running the

Tomas Vanek 148bc7e215 jtag/drivers/bitbang: avoid mostly harmless glitch on SWDIO
bitbang_swd_exchange(rnw=true,...) calls bitbang_interface->swd_write()
with swdio clamped to 0.
bitbang_swd_write_reg() reads 1 turnaround bit, 3 ack bits
and 1 turnaround by one call to bitbang_swd_exchange()
and then switches SWDIO to output.
AFAIK all bitbang interfaces switch SWDIO GPIO direction immediately
in bitbang_interface->swdio_drive().
The GPIO now drives SWDIO line to the value stored in the output register
which is always zero from previous bitbang_swd_exchange(rnw=true,...).
In case the following data bit (bit 0) is 1 we can observe a glitch
on SWDIO:
                                         _____ out 1 ____
HiZ/pull-up ----\                       /
                 \                     /
                  \______ out 0 ______/
          swdio_drive(true)   swd_write(0,1)

The glitch fortunately takes place far enough from SWCLK rising edge
where SWDIO is sampled by the target, so I believe it is harmless
except some corner cases where the reflected wave is delayed on long
line.

Anyway keeping electrical signals glitch free is a good practice.
To keep performance penalty minimal, pre-write the first data
bit to SWDIO GPIO output buffer while clocking the turnaround bit.
Following swdio_drive(true) outputs the pre-written value
and the same value is rewritten by the next swd_write()
instead of glitching SWDIO.

The change increases the speed of the write transfer
from 40 KiB/s to 42 KiB/s @ USB FS, adapter speed 1000.

Tomas Vanek 40bac8e8c4 jtag/drivers/cmsis_dap: improve USB packets filling
DAP write transaction occupies 5 bytes of a command packet.
DAP read transaction needs just one byte in a command packet
and expect 4 bytes in a response.

The fixed maximal number of transactions in a packet caused
packet filling less than optimal.

Compute both command and expected response sizes based on
read or write direction of each transaction.
Run the queue if one of sizes does not fit into a packet.

The change increases the speed of the mostly read transfer
from 36 KiB/s to almost 40 KiB/s @ USB FS, adapter speed 1000
due to reduction of adapter inserted RDBUFF reads.

Antonio Borneo da34e36cdb nds32: drop it, together with aice adapter driver
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.

Tomas Vanek 3da0c2504c jtag/drivers/cmsis_dap: prevent CDC missdetect as CMSIS-DAP bulk
The autodetection of CMSIS-DAP v2 bulk interface is tricky
as not all adapters conform CMSIS-DAP specs.

If an interface has a string descriptor containing CMSIS-DAP,
then OpenOCD did not insisted on the correct interface class
LIBUSB_CLASS_VENDOR_SPEC.

However the relaxed test caused false autodetection of v2 bulk
interface on some CMSIS-DAP v1 adapters with an additional serial
interface with the string descriptor stupidly containing
CMSIS-DAP text.

Make the test less relaxed, refuse autodetection of the interfaces
with the class number of well known functions including CDC and MSC.

Jonathan Bell ee87f2b4a9 jtag/drivers: bcm2835gpio: implement memory barriers when bitbashing
This GPIO driver is common to SoCs that have in-order ARM cores
(BCM2835) as well as superscalar (BCM2836-7) and speculative
out-of-order cores (BCM2711).

For BCM2837 and BCM2711, the processor can dual-issue stores and
is free to merge writes to peripheral memory for pages mapped
MT_NORMAL_NC, which is the default provided by /dev/[gpio]mem.

This can cause glitches (or missing edges) on GPIO pins when
toggled with no delay, as pipelined writes to the same address
can get arbitrarily squelched.

To prevent this happening, make sure the preceding write ops are
flushed outside the shareable domain by using a memory barrier.
