3917823187 openocd: remove NULL comparisons with checkpatch [1/2]
Patch generated automatically through the new checkpatch with
flags "--types COMPARISON_TO_NULL --fix-inplace".
This only fixes the comparisons
	if (symbol == NULL)
	if (symbol != NULL)
The case of NULL on the left side of the comparison is not tested.

Some automatic fix is incorrect and has been massaged by hands:
	-	if (*psig == NULL)
	+	if (*!psig)
changed as
	+	if (!*psig)

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

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:
	sed -i \
	's/(\([A-Z][A-Z0-9_]*\) \([=!]=\) \([a-z][a-z0-9_]*\))/(\3 \2 \1)/g' \
	$(find src/ -type f)

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

eca4f964b4 target/arc: refactor ARC register numbers defines
For Zephyr rtos support it is necessary to define general register
numbers for architecture. There were some already in arc.h file.
Let's define ARC registers numbers as a set instead of separate defines.

Escape the character '<' to prevent doxygen to interpret it as an

1d3d87695c target/register: use an array of uint8_t for register's value
The use of 'void *' makes the pointer arithmetic incompatible with
standard C, even if this is allowed by GCC extensions.
The use of 'void *' can also hide incorrect pointer assignments.

Switch to 'uint8_t *' and add GCC warning flag to track any use of
pointer arithmetic extension.

8fea8460db target/arc: Introduce Actionpoints support
Actionpoint mechanism allows to setup HW breakpoints and watchpoints on Synopsys ARC CPUs.
This mechanism is controlled by DEBUG register and by a set of auxilary registers.
Each actionpoint is controlled by 3 aux registers: Actionpoint(AP) match mask(AP_AMM),
AP match value(AP_AMV) and AP control(AC).

Note: some fields of actionpoint_t structure will be used in further
support of watchpoints.

e2315ccffd coding style: fix space separation

space before comma, before semicolon and between function name and
open parenthesis.
Fix them!

Issue identified using the command

	find src/ -type f -exec ./tools/scripts/checkpatch.pl \
	-q --types SPACING -f {} \;

The patch only changes amount and position of whitespace, thus
the following commands show empty diff
	git diff -w
	git log -w -p
	git log -w --stat

With this commit we introduce L1 and L2 cache

We introduce L2 cache support, which is not presented
on currently support EMSK board. But L2 is presented
on HSDK board, which soon will be introduced.

ea4f98046f target/arc: remove saving context during reset
In arc_poll() function we handle the cases, when jtag indicates, that
processor is halted, but target->state is not TARGET_HALTED.
In case, when processor was halted and target->state was TARGET_RUNNING,
we should save context. At the same time if target->state was TARGET_RESET
we do not need to save context.

Changes: 16.04:
Fix - Move setting target->state = TARGET_HALT after
"target->state == TARGET_RUNNIG" check, otherwise
this check makes no sense

9ee9bdd2f9 Introduce ARCv2 architecture related code
This patch is an initial bump of ARC-specific code
which implements the ARCv2 target(EMSK board) initializing
routine and some basic remote connection/load/continue
functionality.

Changes:
03.12.2019:
-Add return value checks.
-Using static code analizer next fixes were made:
        Mem leak in functions:
                arc_jtag_read_memory,arc_jtag_read_memory,
                arc_jtag_write_registers, arc_jtag_read_registers,
                jim_arc_add_reg_type_flags, jim_arc_add_reg_type_struct,
                arc_build_reg_cache, arc_mem_read.
        Dead code in "arc_mem_read";
        In arc_save_context, arc_restore_context correct arguments
        in"memset" calls.
        In "build_bcr_reg_cache", "arc_build_reg_cache" check
        if list is not empty.

29.12.2019
-Moved code from arc_v2.c to arc.c
-Added checks of the result of calloc/malloc calls
-Reworked arc_cmd.c: replaced spagetty code with functions
-Moved to one style in if statements - to "if(!bla)"
-Changed Licence headers

22.01.2020
-Removed unused variables in arc_common
-Renamed register operation functions
-Introduced arc_deinit_target function
-Fixed interrupt handling in halt/resume:
        * add irq_state field in arc_common
        * fix irq enable/disable calls ( now STATUS32 register is used)
-Switched from buf_set(get)_us32() usage to target_buffer_set(get)_u32()
-Made some cleanup

30.01.2020
-Removed redundant arc_register struct, moved target link to arc_reg_desc
-Introduced link to BCR reg cache in arc_common for freeing memory.
-Now arc_deinit_target frees all arc-related allocated memory.
	Valgrind shows no memory leaks.
-Inroduced arch description in arc.c

01.02.2020
-Remove small memory allocations in arc_init_reg. Instead created reg_value
	and feature fields in arc_reg_desc.
-Add return value for arc_init_reg() func.
-Replaced some integer constants(61,62,63) with defines.
-Removed redundant conversions in arc_reg_get_field().
-Moved iccm/dccm configuration code from arc_configure()
	to separate functions.

19.02.2020
-Change sizeof(struct) to sizeof(*ptr) in allocations
-Changed if/while(ptr != NULL) to if/while(ptr)
-Removed unused variables from struct arc_jtag
-Add additional structs to arc_reg_data_type
 to reduce amount of memory allocations calls
 and simplifying memory freeing.
-Add helper arc_reg_bitfield_t struct which includes
 reg_data_type_bitfield object and char[] name. Reduces
 memory allocations calls.
-Add limit for reg_type/reg_type_field names(20 symbols).
-Add in jim_arc_add_reg_type*() functions additional
 argnument checks(amount of field/name size).
-In jim_arc_add_reg_type*() reduced amount of memory allocations.
-Cleanup of jim_arc_add_reg_type*() functions.
-For commands update ".usage" fields according docopt.
-Cleanup in arc_jtag.c
-Renamed functions which require jtag_exeutre_queue() to arc_jtag_enque_*()
-Add arc_jtag_enque_register_rw() function, which r/w to jtag ir/dr regs
 during regiter r/w.

24.02:
-Change include guards in arc* files according coding style
-Remove _t suffix in struct arc_reg_bitfield_t
-Some cleanup
