Andreas Fritiofson 7a93c9e087 mflash: Remove this broken flash driver
This is causing repeated build failures. Its design is so fundamentally
broken that if someone actually wants to use it, a full rewrite is the
only option. So it's not even worth deprecating in the hope that someone
will notice and fix it, just get rid of it.

Antonio Borneo 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".

Christopher Head 77a8914b7f helper/command: make command_run_line reentrant
The `command_run_line` function contains a comment saying it should be
reentrant. However, it isn’t: it NULLs out `current_target_override` and
doesn’t restore it before returning, and it changes the `context`
associated data of the `interp` object and then deletes that associated
data before returning rather than restoring it to its previous value.

Antonio Borneo 9879f9bf04 jtag: fix error on TCL command "return" in jtag 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 jtag's event only
checks for return code JIM_OK and considers any other value,
including JIM_RETURN, as an error condition.

It can be tested running openocd on a jtag target and adding a
jtag event "setup" with a single line "return", e.g.
	openocd -f board/ti_cc3200_launchxl.cfg \
	-c 'jtag configure cc32xx.cpu -event setup return'
to get the message:
	../src/jtag/core.c:1599: Error:
	in procedure 'jtag_init' called at file "../src/jtag/core.c",
	line 1599

Modify jtag_tap_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.

Antonio Borneo 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.

Tilman Sauerbeck 8ed19a2e29 jtag: drivers: buspirate: chunk SWD switch sequence transfer.
Commit c2e18bfaea changed the size of the JTAG-to-SWD sequence
from 15 bytes to 17 bytes. This broke SWD switch sequence transfer
for buspirate, since buspirate packets can only hold a payload of up
to 16 bytes and we tried to fit the whole sequence in a single packet.

Splitting up the sequence transfer in appropriately sized packets
makes buspirate SWD work again (successfully tested with buspirate
firmwares v6.1 and v7.0).

Tomas Vanek 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.

in 2008's svn://svn.berlios.de/openocd/trunk@975
the script was replaced by the event "old-gdb_program_config" and
the call to jtag_execute_queue() get executed in every case, even
if the event handler was not present.

At last, commit bb3793c9a4
("target: remove legacy target events") stripped away the
obsolete event but left the call to jtag_execute_queue(), now
completely useless.

Remove the call to jtag_execute_queue() and clean-up the code
around it.

Antonio Borneo 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.

Antonio Borneo e26910fdad jtag: simplify management of non-implemented handlers
There is just a single entry point for the jtag API .khz(),
.speed_div(), .power_dropout(), .srst_asserted().

Simplify the code by in-lining the default handler.
The overall code behaviour is not changed.
This change prevents modifying at run-time the content of
struct jtag_interface.

Antonio Borneo 7cddeb0af2 swd: remove unused API frequency()
The specific SWD API to change/query the adapter speed is never
called because the equivalent JTAG API is used in place of it.
In the restructure of struct jtag_interface, the JTAG API is
promoted as global adapter API, thus a specific SWD one is not
anymore required.

Bohdan Tymkiv eea508d9af gdb_server: fix GDB_BUFFER_SIZE usage, fix unaligned access during bulk transfers
Currently size of the GDB buffer is 16384 bytes but it is treated as
nul-terminated string in most of the code, so effective size of the
buffer is actually 16383 bytes. OpenOCD responds with `PacketSize=3fff`
to qSupported request. Result of GDB's `m` command is encoded in hex so
each data byte uses two bytes in the buffer. As a result GDB will split
bulk read requests into chunks 0x1fff bytes each. This causes troubles
on targets (or memory regions) which support only aligned, word-sized
access (such as MMIO buffers).

Steps to reproduce (psoc6 target):
gdb> dump binary memory dump.bin 0x040320000 (0x040320000 + 65536)

OpenOCD:
Error: Failed to read memory at 0x40321ffe
Error: Failed to read memory at 0x40321000
Error: Failed to read memory at 0x40323000
Error: Failed to read memory at 0x40325ffe
Error: Failed to read memory at 0x40329ffa
Error: Failed to read memory at 0x40329ffc
Error: Failed to read memory at 0x4032bffc
Error: Failed to read memory at 0x4032dffa

Consolidate GDB_BUFFER_SIZE usage: ensure size of each buffer is
(GDB_BUFFER_SIZE + 1), add explicit comment that additional byte is used
for nul-termination. Report correct size of the buffer to GDB (0x4000)
as recommended in GDB's docummentation: `if the stub stores packets in a
NUL-terminated format, it should allow an extra byte in its buffer for
the NUL`

Checked with clang-asan, clang-analyzer, valgrind - no new errors.

Antonio Borneo f912649968 helper/command: remove dead code in command_unknown()
Commit 89fa493a3b removes the top
level command "unknown" and adds in command_unknown() some unclear
code that should detect a user-implemented "unknown" command.
But, all the commands that trigger the execution of the function
command_unknown() are registered in register_command_handler() and
have the command name prefixed with "ocd_".
Due to such "ocd_" prefix in cmd_name, the condition
	if (strcmp(cmd_name, "unknown") == 0) { ... }
is always false.
Nobody complained for almost 10 years so we can proceed to remove
this dead code, before merging any change that obsoletes the
prefix "ocd_" and potentially makes the condition true.

Remove the dead code guarded by the condition above.
