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.

08ee7bb982 openocd: fix simple cases of NULL comparison
There are more than 1000 NULL comparisons to be aligned to the

For recurrent NULL comparison it's preferable using trivial

28c24a5c41 openocd: fix simple cases of Yoda condition
There are ~900 Yoda conditions to be aligned to the coding style.
For recurrent Yoda conditions it's preferable using a trivial
script in order to minimize the review effort.
E.g. comparison of uppercase macro/enum with lowercase variable:
	- ...(ERROR_OK == retval)...
	+ ...(retval == ERROR_OK)...

Patch generated automatically with the command:

	$(find src/ -type f)

While there, remove the braces {} around a single statement block
to prevent warning from checkpatch.

efd1d64222 adapter: switch from struct jtag_interface to adapter_driver
To reorganize the adapters code, introduce an adapter_driver
struct that contains all the adapter generic part, while
keeping in two separate struct the specific API jtag_ops and
swd_ops.
Move the allocation of *adapter_driver from the JTAG-specific
file core.c to the more adapter-specific file adapter.c
While splitting the old jtag_interface for every driver, put
the fields in the same order as in the struct declaration so
we keep a consistent code across all the drivers.

While other transport specific API could/would be added as
separate ops, nothing is done here for HLA.

6cb5ba6f11 helper/command: change prototype of command_print/command_print_sameline
To prepare for handling TCL return values consistently, all calls
to command_print/command_print_sameline should switch to CMD as
first parameter.

Change prototype of command_print() and command_print_sameline()
to pass CMD instead of CMD_CTX.
Since the first parameter is currently not used, the change can be
done though scripts without manual coding.
This patch is created using the command:
	sed -i PATTERN $(find src/ doc/ -type f)
with all the following patters:
	's/\(command_print(cmd\)->ctx,/\1,/'
	's/\(command_print(CMD\)_CTX,/\1,/'
	's/\(command_print(struct command_\)context \*context,/\1invocation *cmd,/'
	's/\(command_print_sameline(cmd\)->ctx,/\1,/'
	's/\(command_print_sameline(CMD\)_CTX,/\1,/'
	's/\(command_print_sameline(struct command_\)context \*context,/\1invocation *cmd,/'

This change is inspired by http://openocd.zylin.com/1815 from Paul
Fertser but is now done through scripting.

64f1f7b1c1 Add read buffer to bitbang, improving performance.
Previously for every bit scanned OpenOCD would write the bit, wait for
that bit to be scanned, and then read the result. This involves at least
2 context switches. Most of the time the next bit scanned does not
depend on the last bit we read, so with a buffer we now write a bunch of
bits to be scanned all at once, and then we wait for them all to be
scanned and have a result.

This reduces the time for one testcase where OpenOCD connects to a
simulator from 12.30s to 5.35s!

Running all our tests went from 13m13s to 3m55s.
