firmware refresh the watchdog regularly, in case it has been enabled by previously

the chip bieng programmed.

Description: Potential leak of memory pointed to by 'cmd'
File: /home/vanekt/openocd/scanbuild9/../src/jtag/drivers/ulink.c
Line: 1275

ulink_append_xxx_cmd() functions allocate memory for cmd
and then call ulink_allocate_payload(), which allocates cmd->payload_out
or cmd->payload_in.

ulink_append_queue() checks the size of queue and if the new payload
does not fit, calls ulink_execute_queued_commands() and then
ulink_post_process_queue(). If any of these two fails, an error is
returned, allocated cmd struct leaks and the queue is left in an undefined
state.

Change ulink_append_queue() flow to proceed to appending cmd to the queue
even in the case of fail in previous ulink_execute_queued_commands()
or ulink_post_process_queue(). In case of fail then clear the queue
including the last appended cmd.

Tomas Vanek 46f077aa00 flash/nand/core: fix clang static analyzer warning
core.c:446:
The left operand of '>>' is a garbage value

There are many places where an error code returned from nand->controller
operations are ignored. To keep the change minimal, the error checks are
added only to reading of extended nand info as it was suspected
to be the cause of the warning.

Addition of the error checks did not fix the warning.
scan-build-9 report was inspected and IMHO the warning is bogus:
the term (nand->device->erase_size == 0) cannot give false at line 395
and then evaluate true at line 462. Fixed by zeroing id_buff.

Antonio Borneo 17ac52360f cortex_m: remove deprecation for soft_reset_halt
The command "soft_reset_halt" is deprecated since mid 2013 with
the commit 146dfe3295 ("cortex_m: deprecate soft_reset_halt").
Nevertheless it is still extremely useful with multicore chips
where it allows to reset only one of the cores, option not
available through asserting the chip-wide srst.
It also get useful to handle the reset on some problematic chip,
as in http://openocd.zylin.com/5489

Replace the warning about deprecation with a more light debug
message.

Antonio Borneo 4873503ae4 cortex_a: don't wait for target halted in deassert_reset()
The tcl script src/target/startup.tcl has already the proper
centralized support to wait for all targets to halt after the
command "reset halt". The extra wait in cortex_a_deassert_reset()
is not required.
This extra wait is also an issue for multi-core support, because
waiting for one core to halt can delay the halt request to the
other cores.

Replace the indirect call to cortex_a_halt(), that embeds the wait
for halt, with a low-level halt sequence.

The on-going work on the reset framework is compatible with this
change; in fact it keeps in startup.tcl the wait for targets to
halt, even if current code proposal for cortex_a simply removes
the function cortex_a_deassert_reset().

Antonio Borneo cbbc56f7f7 stlink: remove only instance of useconds_t
The usleep() function, and its associated useconds_t type
specifier, has been obsoleted by POSIX.1-2008.

OpenOCD has 28 call to usleep(), that should be migrated to the
replacement nanosleep(), but due to the different prototype
	int nanosleep(const struct timespec *req, struct timespec *rem);
this can take some effort.

The type useconds_t is used in only one case, where it's used both
as parameter of usleep() and as value passed to LOG_DEBUG(). Due
to different implementation of useconds_t, there are cases that
trigger a compile warning in LOG_DEBUG() when useconds_t is more
than 32 bit.
E.g. with unistd.h in MinGW 4.x, useconds_t is defined as unsigned
long, thus being 32 or 64 bits depending on the target.

Replace the only instance of useconds_t.

In newlib, the argument of isalnum() and the similar functions in
ctype.h is checked to be either an int or an unsigned char.
Using a normal (signed) char triggers a compile time warning
	warning: array subscript has type ‘char’ [-Wchar-subscripts]

Rewrite the function to separate the internal unsigned char
operations from the (signed) char parameter.

Jan Matyas 25efc15069 target: added events TARGET_EVENT_STEP_START and _END
Events TARGET_EVENT_STEP_START and TARGET_EVENT_STEP_END
have been added - analogous to already existing events
TARGET_EVENT_RESUME_*.

This is an example of a concrete use case where having
these events is important:

In RISC-V processors without Debug Program Buffer, OpenOCD
cannot execute fence/fence.i when resuming or single-
stepping. With these events implemented, the user can
instead provide custom operations to achieve that same
effect prior to resuming the processor.

Edward Fewell eb427864e8 tcl/target: Use vectreset for CC13xx/CC26xx targets.
nSRST and sysreqreset are both broken for these targets. Upon a
hard reset, the target disables the TDO/TDI pins and the
ICEPick router will remove the target's TAP from the scan
chain. The scripts to do these tasks are run, but then
OpenOCD throws the reset again breaking the debug connection.

Until that issue can be resolved, vectreset is the only
reset that works without breaking the debug connection.

Update: original patch didn't have the correct reset command.
