Tomas Vanek 4423e05d9d jtag/drivers/jlink: allow SWD multidrop
SW-DPv2 and SWJ-DPv2 devices do not reply to DP_TARGETSEL write cmd.

Ignore the received ACK after TARGETSEL write.

While on it, use swd_ack_to_error_code() for unified error code
translation of the received ACK value for all other commands.

Tomas Vanek b4dd8dbc37 jtag/drivers/bcm2835gpio: use rounding in delay math
After setting adapter speed to some values, the driver
shows the real speed little bit higher.
Although it does not impose a problem from technical point
of view because the difference is smaller than usual speed error,
it looks at least strange to the user. The documentation reads
that real frequency should be same or lower than requested.

Use proper rounding in speed -> delay and delay -> speed
conversions.

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.

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.

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

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.

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.

Tomas Vanek 65de7c95f4 jtag/drivers/kitprog: workaround serious firmware problem
Since commit 88f429ead0
5321: target/cortex_m: faster reading of all CPU registers
debugging with a kitprog adapter freezes at debug entry.

How to replicate:
 openocd -f interface/kitprog.cfg -f target/psoc4.cfg

Connect to telnet server.
Make sure the target is running:
 resume

Halt the target:
 halt

Without this patch OpenOCD freezes in kitprog_hid_command()
in library call hid_write().

Reduce the number of SWD transactions sent in one USB bulk write
as a workaround, simply use shorter buffer.
For details see the comment in src/jtag/drivers/kitprog.c

Antonio Borneo 0d56f379b5 target: add API to temporarily mask target polling
The same flag 'jtag_poll' is currently used as local data for the
command 'poll' and to temporarily mask the target polling.
This can cause unexpected behavior if the command 'poll' is
executed while polling is temporarily masked.

Add a new flag 'jtag_poll_en' to hold the temporarily mask
condition and keep 'jtag_poll' for the 'poll' command only.

While there, change the initial assignment of 'jtag_poll' using
the proper boolean value.
