022e438292 target: Change policy of removing watchpoints/breakpoints.
Now internal watch/breakpoint will not be removed in case
of error during removing triggers from hardware.

Also change signature of some functions (for deletion
bp/wp) to print message in case of some error.

ea0ac6dc77 jtag/drivers/bcm2835gpio: do not configure push-pull inputs as output
Previously, if a pin was configured as ADAPTER_GPIO_INIT_STATE_INPUT and
its drive value was ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL, initialize_gpio
would configure the pin as an output.

The set_gpio_value function is optimized to not set the direction for
pins configured as ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL as it only needs to
be set once. When initialize_gpio performs this setup, it checked only
that the drive value was ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL to set the
output direction but did not exclude input pins which have already had
their direction set.

Now, input pins are ignored when initialize_gpio checks for
ADAPTER_GPIO_DRIVE_MODE_PUSH_PULL to set the mode to output.

3b38226370 mips32: add per-cpu quirks feature
Introduce the ability to detect CPUs based on CP0 PRId register and
apply cpu specific quirks, which alter the default ejtag behavior.

First of those is EJTAG_QUIRK_PAD_DRET, which makes sure extra NOPs are
placed after the DRET instruction on exit from debug mode. This fixes
resume behavior on Ingenic JZ4780 SoC.

The proper detection of some (currently unsupported) CPUs becomes quite
complicated, so please consult the following Linux kernel code when
adding new CPUs:
* arch/mips/include/asm/cpu.h
* arch/mips/kernel/cpu-probe.c

74325dc73d stlink: increase stlink v2 max speed to 2.25 Mbps
stlink v2 on Nucleo-64 board (e.g. NUCLEO-L476RG) has target SWO signal
connected to STM32F103CB'S PA10, which is UART1_RX. UART1 within this
MCU in theory can be configured to 4.5 Mbps baudrate, which means this
is the upper limit supported by HW. As a confirmation BMP (Black Magic
Probe) project also states in documentation that UART1 can be used with
up to 4.5 Mbps baudrate.

Tests have shown that configuring 4.5 Mbps baudrate on stlink v2
available on NUCLEO-L476RG board results in receiving corrupted data.
Using 2.25 Mbps however allows to successfully receive all data from
SWO. This makes sense in terms of STM32F103CB capabilities, since 2.25
Mbps is the next supported baudrate due to division by 2.

Increase supported stlink v2 SWO speed from 2 to 2.25 Mbps.

Tested with NUCLEO-L476RG:

  $ stm32l4x.tpiu configure -protocol uart \
    -traceclk 80000000 -pin-freq 2250000 \
    -output /dev/stdout
  $ stm32l4x.tpiu enable

2.25 Mbps speed confirmed with logic analyzer.

42872d18bf jtag/drivers: dmem: Add Emulated AP mode
This emulation mode supports software translation of an AP request
into an address mapped transaction that does not rely on physical AP
hardware. This is necessary in some hardware such as K3 SoCs since the
hardware architecture anticipates a potential race condition between
AP doing direct memory access generating transactions back to system
bus and firewalls that data path out.

This emulation mode allows direct memory driver to emulate CoreSight
Access Port (AP) and reuse the SoC configuration meant for JTAG
debuggers.

Since the address ranges are flat in nature, the requisite memory base
and size will need to be provided a-priori to the driver for mapping.
The other design alternative would be to map requested memory map for
every register operation, but, that would defeat our intent of getting
max debug performance.

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/

3b78b5c1db libusb_helper: split error and returned value
The USB control transfer can be executed without any data.
The libusb API libusb_control_transfer() can thus be called with
zero 'size', thus returning zero byte transferred when succeed.

The OpenOCD API jtag_libusb_control_transfer() returns zero either
in case of transfer error and in case of libusb_control_transfer()
returning zero, making impossible discriminating the two cases.

Extend jtag_libusb_control_transfer() with separate return value
for error code and explicit parameter's pointer for transferred
bytes.
Make the transferred pointer optional, as many callers do not
properly handle the returned value.
Use 'int' type pointer for transferred, instead of the 'uint16_t'
that would have matched the type of 'size'. This can simplify the
caller's code by using a single 'int transferred' variable shared
with other jtag_libusb_bulk_read|write, while keeping possible the
comparison int vs uint16_t without cast.

This change is inspired from commit d612baacaa
("jtag_libusb_bulk_read|write: return error code instead of size")
