24db985f60 jtag: avoid checking for non NULL pointer to free it
The function free() can be called with a NULL pointer as argument,
no need to check the argument before. If the pointer is NULL, no
operation is performed by free().

Remove the occurrences of pattern:
	if (ptr)
		free(ptr);

f788949651 openocd: fix command's usage string
The usage string should contain only the command parameters.
OpenOCD will automatically prepend the command name to the usage
string while dumping the usage or help message.

Remove the repeated command name from the usage string.

2f62883161 jtag: use proper format with uint32_t
Modify the format strings to properly handle uint32_t data types.

Change the prototype of detect_swo_freq_and_prescaler() in
'jlink.c' to avoid an implicit cast in the caller function.

Change the type of the variable retlen in some functions in
'usb_blaster.c' to properly pass their pointer to the local read
and write functions.

Use the proper parser COMMAND_PARSE_NUMBER(u32, ...).

d493b53e8c jtag/aice: avoid abusing of int32_t type
In several cases the 'int' status value returned by libusb and by
aice internal functions is taken in a variable of type 'int32_t',
requiring an implicit (but trivial) cast.
This makes compulsory using 'PRId32' in the format strings that
print such 'int32_t' result and requires an additional implicit
conversion to return the 'int32_t' as 'int'.

Replace to type 'int' all the occurrences of 'int32_t result' and
fix accordingly the format strings.

Plus, all the size of aice commands are stored as int32_t const
variables with uppercase name, violating the coding style, and are
then passed as 'int' parameter to the read/write functions.

Replace the variables with C macros carrying an 'int' value.

While there, replace also a 'uint32_t' loop index with 'unsigned'
and fix the format string in the loop.

60f104f450 hla_transport: split command registration per transport
All the HLA transports (hla_swd and hla_jtag) register the same
set of commands. Such commands are mainly aimed at handling JTAG
compatibility that is required for the transport hla_jtag only.

Split per transport the command registration and limit the
commands to only those required by the transport itself.
Replace the command "hla newtap" with the transport specific
"swd newdap" or "jtag newtap".
Deprecate the command "hla".

1457a1ab42 tcl/target: use command 'jtag newtap' to add a boundary scan TAP
A JTAG TAP for boundary scan should be added in the scan chain
through the command "jtag newtap".
In some TCL target script the boundary scan TAP is added through
the command "swj_newdap", command that is inappropriate in this
context because specific for arm adi-v5 SWJ-DP.
This situation was probably created to bypass the error with HLA
framework, caused by missing command "jtag newtap".

Add the command "jtag newtap" in HLA, by reusing the existing
code for command "hla newtap".
Fix the TCL target scripts to use the command "jtag newtap" for
the boundary scan TAPs.

The TCL script target/psoc6.cfg has no evident reference to HLA,
so the reason for using "swj_newdap" is less clear. Nevertheless
it uses the wrong command and, once HLA is fixed, there is no
reason to avoid fixing it too.

3ac010bb9f Fix debug prints when loading to flash
While loading to flash with debug level at least 3,
OpenOCD tries to print the whole loaded bitstream.
This will be very-very-slow due to implementation of
conversion from buffer to string.

* fix condition on selected debug level in jtag/core.c
* replace slow buf_to_str function from helper/binarybuffer.c
  with faster but_to_hex_str function

b12fca236d jtag/drivers: add support for Nu-Link (Nuvoton ICE) over usb
Add support for Nu-Link1 over usb hidapi and config file.

The original work is fetched from Nuvoton github.
Code cleanup, fix merge conflicts, compile and runtime issues.
Switch the code from libusb to hidapi, being the device HID based.
Add documentation.
Merge fixes for multi-word memory read.

Reset is not fully compatible with openocd framework; currently
the target is reset and then halt at openocd start.

fb739651c7 cmsis_dap_usb: Support for Microchip's nEDBG CMSIS-DAP interface
This commit fixes support for the nEDBG CMSIS-DAP interface
which is used ie. on the Curiosity Nano SAMD21 board.
nEDBG, similarily to mEDBG, does not support 512 byte HID packets.
This patch adds its USB PID to the exclusion list to make sure that
we stick with the default 64 bytes.

68611efcdf cmsis-dap: fix USB interface for NXP LPC-Link2
The adapter NXP LPC-Link2 is a USB composite device that provides
five interfaces; among three of them that are of HID class, only
one is cmsis-dap.

Accordingly to ticket 255, OpenOCD code is not opening the right
HID interface; then it fails to communicate with the cmsis-dap
while checking the adapter's info.

Unfortunately, hidapi does not provide any support for reading the
string descriptor of the interface, otherwise it would have been
trivial to look for the right cmsis-dap interface.
In fact the cmsis-dap specification reports:
	The CMSIS-DAP Firmware can be also part of a USB composite
	device. If this case, the HID Interface String must
	contain the sub-string CMSIS-DAP.
This requirement is satisfied by the USB device descriptor of the
LPC-Link2 reported below, but cannot be used.

Add a quirk to let OpenOCD only accept interface number zero on a
LPC-Link2 device.

97b7101316 cmsis-dap: prevent hidapi to search again for the adapter
The code in cmsis_dap_usb_open() already searches for the right
HID device that corresponds to the adapter. By calling hid_open()
it asks hidapi to re-search the adapter again based on the VID:PID
and the serial string of the adapter it has just found!

Apart from being a run-time overhead, this has an additional
drawback; there are USB adapters built as composite USB devices
that, beside the cmsis-dap HID interface, have other HID
interfaces for other purposes.
A typical example is the NXP LPC-Link2, that over the 5 interfaces
	0) cmsis-dap (HID)
	1) VCOM-CDC
	2) VCOM-CDC
	3) LPCSIO (HID)
	4) LPC-LINK2 DATA PORT (HID)
has 3 of them of HID class.
The code in cmsis_dap_usb_open() could select the right interface
but then cannot propagate this information to hid_open().

Replace the call to hid_open() with hid_open_path(), passing as
parameter the "unique" path of the HID device already found.

Checking in hidapi source code, the implementation of hid_open()
consists in enumerating the HID devices, scan for the first one
matching VID:PID and serial number, and opening it by calling
hid_open_path(). This analysis highlights that using directly
hid_open_path() should not introduce any regression.

While applying these changes, move hid_init() before enumerating
the HID devices. This has no real consequences because the HID API
is marked as optional but, logically, it should be called before
any other HID API.

6a81bad3b9 configure: split build of hla layouts
Current hla driver supports two "layout": stlink and ti-icdi.
The configure script allows to independently enable/disable the
the two layout. But in reality by selecting only one of them the
whole hla driver is built, including both "layouts".
This is currently not a big issue because the dependencies of the
two layout are the same (libusb), so we are sure that selecting
one of them would permit to build both.
This is going to change with the merge of a third "layout" for
Nuvoton Nu-Link, because it would be based on hidapi.
We need, at least, to decouple the build of libusb and hidapi
"layouts". A full decouple of each "layout" is also welcome to
match the selection done during configure.

Introduce a new automake macro for each of the two "layout" and
use them to conditionally build the "layout" files.
Use the existing autoconf macros to conditionally compile the code
that depends by the "layout".

The old HLA driver for stlink lists SWD as first. The new driver
dapdirect instead lists JTAG, making more difficult a fallback to

Plus, in case of JTAG wiring, SWD is still possible, while the
opposite is not.

ac05f929ed swim: fix adapter speed handling
SWIM transport only supports two adapter speeds:
- "low speed"  equal to 363 kHz (8 MHz / 22)
- "high speed" equal to 800 kHz (8 MHz / 10)

Replace the previous convention that use "0" or "1" for "low" or
"high" speed with the effective speed in kHz.
Rework the implementation of stlink_speed_swim().
Set low speed in the stm8 config files, because only low speed is
permitted at debug connection; the previous code ignores the
initial value.

ac18e960ce swim: abstract the transport in stm8 target
SWIM is implemented by (ab)using the HLA API. This was acceptable
when OpenOCD code did not provided a clear separation between
transports and related APIs. Still today SWIM in OpenOCD is only
supported by STLink, so the decision to re-use the HLA API was the
simpler way to implement it.
After commit efd1d64222 ("adapter: switch from struct
jtag_interface to adapter_driver") the transports API are better
split and SWIM can be implemented as a separate set of API. This
would open the possibility to extend OpenOCD for other adapters
that provide SWIM, e.g. versaloon, or through SPI emulation [1].

Introduce a new set of files swim.[ch] to handle the SWIM API.
Beside the API that almost match the transport low-level data
communication (system_reset, read_mem, write_mem), add a further
API reconnect. Today, inside HLA STLink code, the reconnect is
implemented by hacking the HLA API state(). Please notice that
due to this hack the return type is incorrect; stlink_usb_state()
returns ERROR_OK in SWIM mode, while its return type is enum
target_state. Ignore the type mismatch and still call the HLA API
state in the new SWIM API reconnect. Further commit will fix it.

93c4c0fcbe adapter: expose HLA interface in struct adapter_driver
The transition of STM8/SWIM out of HLA will require a new struct
swim_ops in struct adapter_driver.
To simplify the development, make the HLA interface temporarily
accessible through the struct adapter_driver.
This commit will be reverted after the swim rework.

94dfa68647 stlink: reduce use of hla specific enum hl_transports
In the driver's code it's widely used the enum hl_transports for
any check concerning the current transport, even for the non-hla
transport dapdirect.
The driver already provides a stlink specific enum stlink_mode
that can be used in place of the hla one.

Replace the hla enum with the stlink one allover the code.
Introduce a hla specific wrapper stlink_usb_hl_open() to cope with
the only API that requires the hla specific enum.

The overall behaviour is not changed, with exception for a debug
message in stlink_usb_open() than now prints the numeric value of
stlink enum in place of the numeric value of the corresponding hla
one.

This change prepares the road for moving SWIM transport out of hla
by removing any reference to the macro HL_TRANSPORT_SWIM from the
stlink driver.
