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'
	's/(\([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\) == NULL)/(!\1)/g'
	's/(\([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\) == NULL)/(!\1)/g'

	's/(\([a-z][a-z0-9_]*\) != NULL)/(\1)/g'
	's/(\([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\) != NULL)/(\1)/g'
	's/(\([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\) != NULL)/(\1)/g'

	's/(NULL == \([a-z][a-z0-9_]*\))/(!\1)/g'
	's/(NULL == \([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\))/(!\1)/g'
	's/(NULL == \([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\))/(!\1)/g'

	's/(NULL != \([a-z][a-z0-9_]*\))/(\1)/g'
	's/(NULL != \([a-z][a-z0-9_]*->[a-z][a-z0-9_]*\))/(\1)/g'
	's/(NULL != \([a-z][a-z0-9_]*\.[a-z][a-z0-9_]*\))/(\1)/g'

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.

8850eb8f2c swd: get rid of jtag queue to assert/deassert srst
The transport SWD uses the JTAG queue to assert/deassert the
system reset srst. This is the major inconsistency that has to be
removed to properly split JTAG and SWD.

Introduce a new driver API, reset(), to controls both the signals
trst and srst in the driver, skipping the JTAG queue. Put the new
API in struct jtag_interface, even if in this patch it's used for
SWD only; the goal is to get it reused by the other transports.

Add the implementation of the API in all the drivers that
implement SWD. Such implementation is almost the same of the old
code in JTAG queue.

Create a wrapper adapter_system_reset() to use the new API and
remove the SWD specific swd_add_reset(). In the wrapper replace
jtag_add_sleep() with jtag_sleep(), because the former uses the
JTAG queue too.
Rename the old jtag_add_reset() as legacy_jtag_add_reset() with
the target to remove it when all drivers would be ported to the
new reset API. Create a new jtag_add_reset() that calls the
legacy function for drivers still on the old reset API.

Use the new API also on JTAG transport for the drivers that can
support both SWD and JTAG.

For the moment, do not modify the implementation of JTAG-only
drivers, which will continue using the usual method. This should
be cleaned-up in future commits.

8ed19a2e29 jtag: drivers: buspirate: chunk SWD switch sequence transfer.
Commit c2e18bfaea changed the size of the JTAG-to-SWD sequence
from 15 bytes to 17 bytes. This broke SWD switch sequence transfer
for buspirate, since buspirate packets can only hold a payload of up
to 16 bytes and we tried to fit the whole sequence in a single packet.

Splitting up the sequence transfer in appropriately sized packets
makes buspirate SWD work again (successfully tested with buspirate
firmwares v6.1 and v7.0).

When it's not needed, we can now omit adapter_khz in

for speed_div and khz functions.

It also removes calls to adapter_khz in interface configuration
files when not used anymore.
