Evgeniy Naydanov ea7e17491d [NFC] target/riscv: refactor `init_registers()`
The logic in `init_registers()` was quite convoluted.
Initialization of each `struct reg` field is separated into function
`gdb_regno_<field_name>()`.
IMHO, this makes it much easier to reason about the code.

Antonio Borneo 07141132a7 gdb_server: don't send unrequested ACK at connection
On 2008-03-05, before git's age, commit 6d95014674 adds sending
an ACK ('+' char) at GDB connection, before receiving any GDB
remote command that requires to be ACK'ed.

Neither the text added in the commit message ("added ACK upon
connection (send +)") nor in the associated comment ("send ACK to
GDB for debug request") provide an exhaustive explanation for
sending this unsolicited ACK.

This code has never been touched since its introduction.

Analysis of GDB code doesn't show it's required, including old GDB
code.
Running gdbserver (from GDB package) and attaching it with "nc"
shows that gdbserver does not send any ACK to a new connection.
Same for lldb-server.

Drop it!

SydMontague 179169268c jtag/commands: fixed buffer overflow
When performing a command queue allocation larger than the default page
size of 1MiB any subsequent allocations will run into an integer under-
flow when checking for the remaining memory left in the current page.
Causing the function returning a pointer past the end of the buffer and
thus creating a buffer overflow.

This has been observed to cause some transfers to Efinix FPGAs to fail,
because another buffer can get corrupted in the process, causing its
respective free() to fail.

N S c6e7e48b05 jtag/drivers: fix reset logic handling in OpenJTAG
The OpenJTAG driver behaviour always forces a system reset on jtag_init.
The driver was incorrectly assuming that when execute_reset is called
with trst set to 1 - perform a software TAP reset, otherwise perform a
system reset when trst is 0.

The set_state call assumes the that OpenJTAG hardware will perform a
software TLR reset if the target state is TAP_RESET. This is not the
case: the published VHDL will simply find the shortest path to TLR and
not perform a fixed 5 cycle operation with TMS held high.

Fix the code to only perform system resets when srst is 1 in
execute_reset and to force a software TAP reset operation in set_state
when the target state is TAP_RESET.

Parshintsev Anatoly 50be4bd267 jtag/mpsse: mpsse_flush should not treat LIBUSB_ERROR_INTERRUPTED as an error
LIBUSB_ERROR_INTERRUPTED can happen when (among other things) OpenOCD
process receives a signal like SIGHUP or SIGINT during a call to libusb.
Such situations are expected and should not be treated as an error - the
affected request should just be restarted.

Without this patch applied if a signal arrives during FTDI initialization
procedure we can easily end up (if JTAG speed is low) in situations like
https://review.openocd.org/c/openocd/+/4767. This happens because
fpsse_flush fails due to LIBUSB_ERROR_INTERRUPTED .

It should be noted that the current usage of mpsse_flush should be
revised since it seems that we don't always process error codes returned
by the function.

Tomas Vanek 226085065b target/cortex_m: drop useless target_halt() call
In 2008 the commit 1829361253 ("define resetting
the target into the halted or running state as an atomic operation.")
introduced the target_halt() call to the end of cortex_m3_assert_reset(),

Checkpatch-ignore: GIT_COMMIT_ID

A year later the commit ed36a8d15d
("... Updated halt handling for cortex_m3")
prevented cortex_m3_halt() take any action in case of TARGET_RESET state.
This narrowed the target_halt() called from cortex_m3_assert_reset()
to setting target->halt_issued and storing a time stamp.

Introducing ocd_process_reset(_inner) made the setting of halt_issued
and halt_issued_time useless. The Tcl function waits for halt
of all targets if applicable.

cortex_m_halt() and also target_halt() does not work as expected
if the cached target state is TARGET_RESET (although the core could
be out of reset and ready to be halted, just have not been polled).
Explicit Tcl arp_poll must be issued in many scenarios.

Remove the useless hack.

Also remove the explicit error return from cortex_m_halt_one()
in case of RESET_SRST_PULLS_TRST and asserted srst. If the communication
with the target is gated by any reset, cortex_m_write_debug_halt_mask()
fails. Propagate the error return of this call instead.

Prevent to do so on targets with defer_examine,
as such targets need some special handling to enable them

The change makes possible to handle a multicore Cortex-M SoC with
an auxiliary Cortex-M core(s) switched of by default

Vincent Fazio 0d3d4c981a jtag/adapter: retype adapter_gpio_config.{gpio,chip}_num
Previously, the gpio_num and chip_num members of adapter_gpio_config
were typed as 'int' and a sentinel value of -1 was used to denote
unconfigured values.

Now, these members are typed as 'unsigned int' to better reflect their
expected value range.

The sentinel value now maps to UINT_MAX as all adapters either define an
upper bound for these members or, in the case of bcm2835gpio, only
operate on a specific chip, in which case the value doesn't matter.

Format specifiers have been left as %d since, when configured, valid
values are within the positive range of 'int'. This allows unconfigured
values to display as a more readable value of -1 instead of UINT_MAX.

Ahmed BOUDJELIDA 0c2d907a5d contrib/firmware: Change USB interruption handling for JTAG/I2C communications
Before this change, when we send an I2C Bulk data at the same
time while Jtag bitbanging functions execute, the microcontroller
puts JTAG bitbanging on wait and executes all I2C bitbanging
function, which causes problems like loss of Ack in DAP responses
and other errors.

With this commit, When I2C interruption occurs, it sets a variable
to true and continues JTAG bitbanging, when it finish it executes
the I2C bitbang.

Ahmed BOUDJELIDA ba860abcab jtag/drivers: Add GPIO extender configuration function to ANGIE driver
Add GPIO extender initial configuration that is needed to configure
some important GPIOs and ensure that the dev board is ready to work.

Add i2c_write function that make a write transfer to any slave device.

Give a new Product ID to ANGIE to make it different than the non
programmed ANGIE.

Ahmed BOUDJELIDA da6c0e45a2 contrib/firmware: Add direction control for 'SCL' i2c signal
We want to keep the tri-state buffers located between the FPGA
and the board, in 'Z' state until we launch an i2c connection.

We launch an i2c start condition, make the SCL
direction 'OUT' to start the i2c protocol and at the end
of the i2c connection at the stop condition, we re-make
the tri-state buffers at 'Z' state.

every clock cycle (every byte sent) until reaching zero and stops.
