be2d25efcc arm_adi_v5: add API send_sequence() and use it
The method to send an arbitrary sequence to DAP depends on the
transport and is thus different on JTAG and SWD. This is already
coded in dap_to_jtag() and dap_to_swd().

Add a new API send_sequence() in struct dap_ops.
Add the implementations of send_sequence() in adi_v5_jtag.c and
adi_v5_swd.c
Rewrite dap_to_jtag() and dap_to_swd() using the new API.
Move the enum swd_special_seq in arm_adi_v5.h to solve a circular
dependencies among swd.h and arm_adi_v5.h

2dc88e1479 target/armv7m_trace: Improve SWO frequency auto-detection
The SWO frequency auto-detection with J-Link adapters does not work
properly in the current implementation. This is because the trace layer
has only information about the highest possible SWO frequency supported
by the adapter. With that the trace layer calculates the SWO prescaler
which usually leads to a frequency deviation greater than what is
permitted by J-Link adapters.

Move the calculation of the SWO prescaler from the trace layer into the
trace configuration of the adapter to overcome this problem.
The adapter has the necessary information to choose a suitable SWO
frequency and calculate the corresponding prescaler that complies with
the maximum allowed frequency deviation.

Tested with:
  - STM32L152RC Discovery Kit (ST-Link)
  - EFM32GG-STK3700 (J-Link)

f476c9eec4 gdb_server: fix string length with semihosting_fileio
The GDB file-I/O remote protocol extension, used for implementing
the semihosting file I/O, requires the length of strings to
include the trailing zero character, as explicitly stated inside a
comment in GDB source code [1]:
	/* 1. Parameter: Ptr to pathname / length incl. trailing zero.  */

ARM specification for semihosting [2] requires the string length
to not include the trailing zero character, e.g. in SYS_OPEN
specifications:
	"field 3: An integer that gives the length of the string
	 pointed to by field 1. The length does not include the
	 terminating null character that must be present."

The mismatch above requires OpenOCD to add "one" to the string
length before passing it to GDB. Such conversion is missing
either in the generic semihosting provider of the data, the
function semihosting_common(), and in the consumer of the data,
the gdb_server function gdb_fileio_reply().
The conversion is already implemented in the target specific
function nds32_get_gdb_fileio_info(), but it's not the preferred
place for such GDB specific requirement.

This issue affects the semihosting calls "open", "unlink",
"rename" and "system".

Remove the "+1" conversion from nds32_get_gdb_fileio_info().
Add the "+1" conversion in gdb_fileio_reply().

5dc5ed5714 target/cortex_a: use aligned accesses for read/write cpu memory slow
Armv7a is able to read and write memory at un-aligned address, but
only when bit SCTLR.A (Alignment check enable) is zero and the
address belongs to a memory space with attribute "Normal" (see [1]
chapter A3.2.1 "Unaligned data access"). In all the other cases
the memory access will trigger an alignment fault data abort
exception.
Memory attributes are explained in [1] chapter A3.5 "Memory types
and attributes and the memory order model".

Disabling the MMU cause a change in memory attribute, as explained
in [1] chapter B3.2 "The effects of disabling MMUs on VMSA
behavior".
This can cause several issues. e.g. a SW breakpoint on un-aligned
4-byte Thumb instruction, set when MMU is on, can be impossible to
remove when MMU turns off.

While is possible to check all the possible conditions before an
un-aligned memory access, it's clearly more maintainable to skip
such complexity and only perform aligned accesses.

Check the alignment and eventually modify the data size before
calling the functions cortex_a_{read,write}_cpu_memory_slow().
Change the comment in the two functions above to comply with the
new behaviour.

5f42124a40 adi_v5_jtag: avoid RAM exhaustion by limiting jtag queue size
Issue has been found when I tried to read 64 MiB QSPI flash bank.
Bank is memory mapped, default_flash_read() is used for 'flash read_bank'
command. OpenOCD consumed as much as 6.8 GiB of RAM during this
process. Investigation showed that this happens because JTAG queue
is not limited in any way. OpenOCD queues 16 millions of AP reads
allocating all corresponding data structures.

Most of this memory is allocated in:
cmd_queue_alloc (commands.c) - 4.2 GiB
dap_cmd_new (adi_v5_jtag.c) - 2.25GiB

This patch implements a pool of "struct dap_cmd" objects using
linked list. Objects are taken from a pool in "dap_cmd_new()" and
returned to the pool when they are not needed. Size of the pool
is limited to 64K of objects, JTAG queue is forcibly executed
when this limit is reached.

Checked with Valgrind and Clang analyzer - no new warnings.

f545044c2a target: Switch to target_read_buffer() in verify_image fallback

aligned.

Instead use the target_read_buffer() function which is for exactly this
purpose and generates optimal accesses with natural alignment.

2. Add set_reg() to rtos. gdb_server uses this to change a single

3. Add target_get_gdb_reg_list_noread() so it's possible for gdb to get
a list of registers without attempting to read their contents.

6ea43726a8 cortex_m: set C_DEBUGEN in 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.
Without a better replacement of the command, it's worth fixing it.

Accordingly to ARM DDI 0403E.d, chapter C1.4.1 "Entering Debug
state on leaving reset state", to halt the core at reset both bits
DHCSR.C_DEBUGEN and DEMCR.VC_CORERESET must be set.
Current code only sets the latter bit, relying on having C_DEBUGEN
already set through other commands, e.g. "halt". This prevents the
command "soft_reset_halt" to work if issued as very first command.

Set the bit C_DEBUGEN in command "soft_reset_halt".

1af83682e0 target: fix error on TCL command "return" in target event handler
The TCL command "return" always returns error code JIM_RETURN, to
indicate that the effective error code and message are elsewhere.

In the current implementation, the caller of target's event only
checks for return code JIM_OK and considers any other value,
including JIM_RETURN, as an error condition, thus dumping the
call-trace. The execution is not stopped because the error is not
further propagated, but the error message is annoying and
misleading.

It can be tested running
	openocd -f ./test.cfg
using the following script "test.cfg". You can replace the board
file in line 1, to use a board available in your lab:
  1	source [find board/st_nucleo_f4.cfg]
  2	[target current] configure -event reset-start {}
  3	[target current] configure -event reset-end {return}
  4	init
  5	proc a {} {[target current] invoke-event reset-start}
  6	proc b {} {[target current] invoke-event reset-end}
  7	proc c {} {a;b;echo "arrived at the end"}
  8	c
  9	shutdown
The execution produces:
	./test.cfg:7: Error:
	in procedure 'c' called at file "./test.cfg", line 8
	in procedure 'b' called at file "./test.cfg", line 7

	arrived at the end
that shows the call-trace but does not halt the execution.

The developer can avoid using the "return" command in the event
body by defining a TCL procedure that implements the handler and
that contains the "return" command, reducing the handler body to
a simple call to the procedure above. But this approach is either
not documented nor always intuitive while writing the handler,
causing waste of time to look for the false error.

Modify target_handle_event() to detect the specific return value
of the "return" command and to test the real error code that is,
eventually, specified to the TCL "return" command.

20396e56b7 target: make target re-configuration possible again
Before commit 877cec20dc
("command: check command mode for native jim commands") all the jim commands
were erroneously treated as they had mode COMMAND_ANY.

The command '$_TARGET configure -xxx' was therefore applicable on running
OpenOCD to change the target configuration. It is handy e.g. for changing
an event handler or changes of the work area.

Change 'configure' command .mode to COMMAND_ANY to make it possible again.

The only parameter which cannot be re-configured after init is -gdb-port.
Test the command mode and refuse setting of gdb port after init.

215f14bec8 target/armv7m: fix register number in armv7m_get_core_reg()
armv7m_get_core_reg() calls arm->read_core_reg()
arm->read_core_reg() expects the register number as an index
to core reglist, not an ARMv7M specific register code.
Use reg->number instead of armv7m_reg->num.

The change solves assert
  src/target/armv7m.c:222: armv7m_read_core_reg: Assertion
  `num < (int)armv7m->arm.core_cache->num_regs' failed.
when gdb 'info reg' is issued on a Cortex-M target and
no cortex_m_debug_entry() has been called since OpenOCD start
(target was halted before OpenOCD start).

02cd1e39cc target/cortex_m: remove dependency from jtag queue
Since the first commit 09883194f8 that introduced cortex_m, the
code has a delay of 50ms after srst has been asserted.
The specific delay is implemented through the JTAG_SLEEP command
sent in the jtag queue.

To remove the dependency from the jtag queue, replace the delay
with a transport independent function.

In case of jtag transport, this change keeps the same behaviour
only if the jtag queue has been flushed before the delay. This
does not happen if the call to dap_dp_init(), few lines above,
fails while calling a dap_queue_dp_{read,write}(); in this case
the jtag queue will be flushed later, after the delay, while in
the original code the delay would follow the flushing of the
commands already queued. Anyway, this different behavior would
only happen in case of DAP already not responsive so anticipating
the delay in such error condition is not supposed to add further
problems.

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.
