As stated in ARM v8-A Architecture Reference Manual (ARM DDI 0487E.a)
in Chapter H4.3 DCC and ITR access modes:
Writes to EDITR trigger the instruction to be executed if the PE
is in Debug state:
- If the PE is in AArch64 state, this is an A64 instruction.
- If the PE is in AArch32 state, this is a T32 instruction
But in armv8_opcodes specifically in t32_opcodes we were using some
A32 instructions for HLT, LDRx and STRx opcodes.
Using the correct LDRx and STRx opcodes, fixes 16 and 8 bits memory access
when the PE is in AArch32 state.

Before this patch aarch64_set_breakpoint was using either A64, or A32
HLT opcode by relying on armv8_opcode helper.
This behaviors ignores the fact that in AArch32 state the core could
execute Thumb-2 instructions, and gdb could request to insert a soft
bkpt in a Thumb-2 code chunk.
In this change, we check the core_state and bkpt length to know the
correct opcode to use.
Note: based on https://sourceware.org/gdb/current/onlinedocs/gdb/ARM-Breakpoint-Kinds.html
if bkpt length/kind == 3, we should replace a 32-bit Thumb-2 opcode,
then we use twice the 16 bits Thumb-2 bkpt opcode and we fix-up the
length to 4 bytes, in order to set correctly the bpkt.

when using step command from gdb the step happens without any issue,
but aarch64_step call explicitly aarch64_poll which consumes the
status change to HALTED, so it does not inform gdb that the step has
finished.
by removing this call, all is back to normal and openocd could inform gdb
that the step has finished.

in"memset" calls.
In "build_bcr_reg_cache", "arc_build_reg_cache" check
if list is not empty.

-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

-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.

find src/ -type f -exec ./tools/scripts/checkpatch.pl \
-q --types POINTER_LOCATION --fix-inplace -f {} \;
then manually reviewed.
OpenOCD coding style does not mention the space around pointer's
asterisk, so no check is enforced. This patch only makes the style
uniform across the files.
The patch only changes amount and position of whitespace, thus
the following commands show empty diff
