Tim Newsome 3ba21e5f00 target/riscv: calloc() memory per register.
This replaces a static array with 8 bytes per register. When there are
vector registers larger than 8 bytes, they would end up clobbering each
other's values. I can't believe I didn't catch this earlier.

See https://github.com/riscv/riscv-openocd/pull/658

Tomas Vanek f735faa931 target,flash: allow target_free_working_area on NULL area pointer
Standard C library free() allows NULL pointer as a parameter.

Change target_free_working_area() to conform this convention.

Remove NULL pointer tests before target_free_working_area() calls.

While on it add missing setting pointer to NULL after target_free_working_area().

Memory sample and repeat read functionality was left out of this change

Yasushi SHOJI 05752557dd helper: Remove src/helper from include dirs
The header files under src/helper/ can currently be included with
either

    #include <bits.h>
    or
    #include <helper/bits.h>

This is because we specify both "src/" and "src/helper/" directories
as include directories.  Some files name under "src/helper/", such as
types.h, log.h, and util.h are too generic and could be ambiguous
depending on the search path.

This commit remove "src/helper/" from our include dir and make C files
include explicitly.

Antonio Borneo 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)

Tim Newsome b68674a1da Upstream tons of RISC-V changes.
These are all the changes from https://github.com/riscv/riscv-openocd
(approximately 91dc0c0c) made just to src/target/riscv/*. Some of the
new code is disabled because it requires some other target-independent
changes which I didn't want to include here.

Built like this, OpenOCD passes:
* All single-RV32 tests against spike.
* All single-RV64 tests against spike.
* Enough HiFive1 tests. (I suspect the failures are due to the test
suite rotting.)
* Many dual-RV32 (-rtos hwthread) against spike.
* Many dual-RV64 (-rtos hwthread) against spike.

I suspect this is an overall improvement compared to what's in mainline
right now, and it gets me a lot closer to getting all the riscv-openocd
work upstreamed.

The function free() can be called with a NULL pointer as argument,
no need to check the argument before. If the pointer is NULL, no
operation is performed by free().

Remove the occurrences of pattern:
	if (ptr)
		free(ptr);

In target/openrisc/jsp_server.c, an error is logged if the ptr was
already NULL. This cannot happen since the pointer was already
referenced few lines before and openocd would have been already
SIGSEGV in that case, so remove the log.

Tarek BOCHKATI a99bf2ea94 semihosting: reorganize semihosting commands
the same semihosting handlers chain is declared twice:
 1. in src/target/armv4_5.c
 2. in src/target/riscv/riscv.c

to make it simpler we moved the declaration into
'src/target/semihosting_common.c' under semihosting_common_handlers[].
then we used this into both of armv4_5.c and riscv.c

Antonio Borneo e7306d361b coding style: fix space around pointer's asterisk
The script checkpatch available in new Linux kernel offers an
experimental feature for automatically fix the code in place.
While still experimental, the feature works quite well for simple
fixes, like spacing.

This patch has been created automatically with the script under
review for inclusion in OpenOCD, using the command
	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
	git diff -w
	git log -w -p
	git log -w --stat

Antonio Borneo 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.

While initializing struct command_registration, the field's name "name"
is not specified, thus relying on the fact that it is the first field
declared in the struct and it's initialization value can be listed as
the first one.

Be coherent in the struct initialization and always use the field's
name.

This represents months of continuing RISC-V work, with too many changes
to list individually. Some improvements:
* Fixed memory leaks.
* Better handling of dbus timeouts.
* Add `riscv expose_custom` command.
* Somewhat deal with cache coherency.
* Deal with more timeouts during block memory accesses.
* Basic debug compliance test.
* Tell gdb which watchpoint hit.
* SMP support for use with -rtos hwthread
* Add `riscv set_ir`

This supports both 0.11 and 0.13 versions of the debug spec.

Support for `-rtos riscv` will come in a separate commit since it was
easy to separate out, and is likely to be more controversial.

Flash support for the SiFive boards will also come in a later commit.
