eb56509fa4 openocd: src/jtag: replace the GPL-2.0-or-later license tag
Replace the FSF boilerplate with the SPDX tag.

The SPDX tag on files *.c is incorrect, as it should use the C99
single line comment using '//'. But current checkpatch doesn't
allow C99 comments, so keep using standard C comments, by now.

248161cbf4 jtag/cmsis_dap: switch to command 'adapter serial'
The driver cmsis_dap defines the command 'cmsis_dap_serial' to
specify the serial string of the adapter.

Remove and deprecate the driver command, and use 'adapter serial'.

277b0a5d97 jtag/cmcis_dap: use COMMAND_PARSE_NUMBER in command handlers
the usage of COMMAND_PARSE_NUMBER is safer in COMMAND_HANDLERs since it provides
better error checking than strto** functions.

08ee7bb982 openocd: fix simple cases of NULL comparison
There are more than 1000 NULL comparisons to be aligned to the
coding style.
For recurrent NULL comparison it's preferable using trivial
scripts in order to minimize the review effort.

Patch generated automatically with the command:
	sed -i PATTERN $(find src/ -type f)
where PATTERN is in the list:
	's/(\([a-z][a-z0-9_]*\) == NULL)/(!\1)/g'

87c90393fe Cleanup of config/includes.
Remove a use of AH_BOTTOM from configure.ac. This macro is used by
autoheader to add '#include' of some include file to the end of
config.h.in and then to config.h. OpenOCD can be built with a custom
config.h, so it's preferable to move these '#include' statement directly
in the C files that need them dropping this unneeded dependency.

It also causes problems when I want to use the gnulib library (which
comes with its own Makefile, and does not have the same include path as
the top-level Makefile).

So this change touches a lot of files, but is actually really simple. It
does not affect functionality at all.

11d918d9c1 libusb: don't use typedef's
Libusb defines both the struct and a typedef to the struct using
the same struct name. It's then possible to use either 'struct x'
and 'x'. E.g.:
	typedef struct libusb_device libusb_device;

OpenOCD is not consistent and uses a mix of 'struct x' and 'x'.

To make OpenOCD code uniform, stick at project's coding style and
use 'struct x' in place of the typedef'd name.

01030fb893 drivers/cmsis-dap: tidy up buffer access
Each one of CMSIS-DAP command handlers was responsible for setting
HID report number, which in case of USB bulk transport was not used
at all. The command had to be filled with 1 byte offset whereas
the response was read without an offset.

Introduce 'command' and 'response' pointers into struct cmsis_dap.
Use them for filling the command and read the response respectively.
CMSIS-DAP command parameter are now at positions as documented in
https://arm-software.github.io/CMSIS_5/DAP/html/group__DAP__Commands__gr.html
Adjust buffer allocation for HID and USB bulk transports.

While on it, use h_u32_to_le() and h_u16_to_le() instead of per-byte
writes.

fed42ccfd3 cmsis-dap: don't update the packet size across backends.
The hidapi cmsis-dap backend is using a packet_size of
64+1: 64 is the bMaxPacketSize0 and 1 is the hid Report-Id.

In hidapi::hid_write(), the packet_size is decremented by 1 and
stored for the next transfer.
The packet_size is now valid bMaxPacketSize0=64,
so when hid_read() is called, libusb_bulk_transfer() finishes w/o timeout.

For the libusb bulk backend, the same packet_size of 64+1 is used,
but there's no hid_write() to decrement and store it for the next read.

So the next time a read is done, it will try to read 64+1 bytes.

Fix this by putting the packet logic within each backend.
Use calloc() to allocate the struct cmsis_dap to be on safer side.

e6770f1ab6 jtag/drivers/cmsis_dap: fix usb bulk connection logic
http://openocd.zylin.com/4831 has following problems in selecting
USB device/interface to connect:
- attempts connection to any device with user class and 2 bulk endpoints
- regardless of cmsis_dap_vid_pid or cmsis_dap_serial setting
  connects to the first suitable device

Distinguish between real match and no filtering cases and use that info
appropriately.

Add debug messages to show why the interface is refused.

Move CMSIS-DAP interface string detection before checking of class/endpoints
to give more understandable debug log in the case the device is refused.

Keep track of reliable matches in both device and interface enumeration.
First search for the interface with CMSIS-DAP in the interface string.
If it fails, chose the first suitable interface.

8f927d5164 Add CMSIS-DAP v2 support
This change implements CMSIS-DAP v2 which works with raw USB bulk transfers.

The old driver is now split into a generic CMSIS part and a HID backend,
with a new raw USB backend for CMSIS-DAP v2.

New commands:
- cmsis_dap_backend (usb_bulk | hid | auto)
- cmsis_dap_usb interface <interface number>
