* flash/nor: Add support for TI CC26xx/CC13xx flash

Added cc26xx flash driver to support the TI CC26xx and CC13xx
microcontrollers. Driver is capable of determining which MCU
is connected and configures itself accordingly. Added config
files for four specific variants: CC26x0, CC13x0, CC26x2, and
CC13x2.

Note that the flash loader code is based on the sources used
to support flash in Code Composer Studio and Uniflash from TI.

Removed cc26xx.cfg file made obsolete by this patch.

* flash/nor/nrf5: remove is_erased setting and autoerase before write

Cached flash erase state in sectors[].is_erased is not reliable as running
target can change the flash.

Autoerase was issued before flash write on condition is_erased != 1
Remove autoerase completely as it is a quite non-standard feature.

* tcl/target/stm32f7x: configure faster system clock in reset-init

STM32F7xx devices need faster clock for flash programming
over JTAG transport. Using reset default 16 MHz clock
resulted in lot of DAP WAITs and substantial decrease
of flashing performance.

Adapted to the restructured dap support

* jtag/drivers/cmsis-dap: fix connect in cmsis_dap_swd_switch_seq()

The proc cmsis_dap_swd_switch_seq() is part of the SWD API for
this interface driver. It is valid only when the interface is
used in SWD mode.
In this proc there is the need to call, in sequence, first
cmsis_dap_cmd_DAP_Disconnect() then cmsis_dap_cmd_DAP_Connect().
The latter call requires the connection mode as parameter, that
inside cmsis_dap_swd_switch_seq() can only be CONNECT_SWD.

The current implementation is not correct and in some cases can
pass mode CONNECT_JTAG. Moreover, JTAG is optional in CMSIS-DAP
and passing mode CONNECT_JTAG triggers an error with SWD-only
interfaces.

Use mode CONNECT_SWD in SWD specific cmsis_dap_swd_switch_seq().

errors that occur during non-algorithm work (erasing, programming

stm32x_wait_status_busy in those cases. Correct a log message

* gdb_server: only trigger once the event gdb-detach at gdb quit

When GDB quits (e.g. with "quit" command) we first execute
gdb_detach() to reply "OK" then, at GDB disconnect (either TCP
or pipe connection type), we execute gdb_connection_closed().
In case GDB is killed or it crashes, OpenOCD only executes the
latter when detects the disconnection.
Both gdb_detach() and gdb_connection_closed() trigger the event
TARGET_EVENT_GDB_DETACH thus getting it triggered twice on clean
GDB quit.

Do not trigger the event TARGET_EVENT_GDB_DETACH in gdb_detach()
and let only gdb_connection_closed() to handle it.

* gdb_server: set current_target from connection's one

In a multi-target environment we are supposed to have a single
gdb server for each target (or for each group of targets within
a SMP node).
By default, the gdb attached to a server sends its command to
the target (or to the SMP node targets) linked to that server.

This is working fine for the normal gdb commands, but it is
broken for the native OpenOCD commands executed through gdb
"monitor" command. In the latter case, gdb "monitor" commands
will be executed on the current target of OpenOCD configuration
script (that is either the last target created or the target
specified in a "targets" command).

Fixed in gdb_new_connection() by replacing the current target
in the connection's copy of command context.

* server: Improve signal handling under Linux

Commit 5087a955 added custom signal handlers for the openocd
server process.

Before this commit, when openocd is run as a background process
having the same controlling terminal as gdb, Control-C would be
handled by gdb to stop target execution and return to the gdb prompt.

However, after commit 5087a955, the SIGINT caused by pressing
Control-C also terminates openocd, effectively crashing the
debugging session.  The only way to avoid this is run openocd in
a different controling terminal or to detach openocd from its
controlling terminal,
thus losing all job control for the openocd process.

This patch improves the server's handling of POSIX signals:
1) Keyboard generated signals (INT and QUIT) are ignored
   when server process has is no controlling terminal.
2) SIGHUP and SIGPIPE are handled to ensure that .quit functions
   for each interface are called if user's logs out of X
   session or there is a network failure.

SIG_INT & SIG_QUIT still stop openocd
when it is running in the foreground.

* armv7a: read ttbcr and ttb0/1 at every entry in debug state

Commit bfc5c764df avoids reading
ttbcr and ttb0/1 at every virt2phys translation by caching them,
and it updates the cached values in armv7a_arch_state().
But the purpose of any (*arch_state)() method, thus including
armv7a_arch_state(), is to only print out and inform the user
about some architecture specific status.
Moreover, to reduce the verbosity during a GDB session, the
method (*arch_state)() is not executed anymore at debug state
entry (check use of target->verbose_halt_msg in src/openocd.c),
thus the state of translation table gets out-of-sync triggering
	Error: Address translation failure
or even using a wrong address in the memory R/W operation.

In addition, the commit above breaks the case of armv7r by
calling armv7a_read_ttbcr() unconditionally.

Fixed by moving in cortex_a_post_debug_entry() the call to
armv7a_read_ttbcr() on armv7a case only.
Remove the call to armv7a_read_ttbcr() in armv7a_identify_cache()
since it is (conditionally) called only in the same procedure
cortex_a_post_debug_entry().

* arm_adi_v5: put SWJ-DP back to JTAG mode at exit

When SWD mode is used, current OpenOCD code left the SWJ-DP in
SWD mode at exit. Also, current code is unable to switch back the
SWJ-DP in JTAG at next run, thus a power cycle of both target and
interface is required in order to run OpenOCD in JTAG mode again.

Put the SWJ-DP back to JTAG mode before exit from OpenOCD.

Use switch_seq(SWD_TO_JTAG) instead of dap_to_jtag(), because the
latter is not implemented on some interfaces. This is aligned
with the use of switch_seq(JTAG_TO_SWD) in swd_connect().

* server: explicitly call "shutdown" when catch CTRL-C or a signal

Every TCL command can be renamed (or deleted) and then replaced by
a TCL proc that has the same name of the original TCL command.
This can be used either to completely replace an existing command
or to wrap the original command to extend its functionality.
This applies also to the OpenOCD command "shutdown" and can be
useful, for example, to set back some default value to the target
before quitting OpenOCD.
E.g. (TCL code):
	rename shutdown original_shutdown
	proc shutdown {} {
		puts "This is my implementation of shutdown"
		# my own stuff before exit OpenOCD
		original_shutdown
	}

Unfortunately, sending a signal (or pressing CTRL-C) to terminate
OpenOCD doesn't trigger calling the original "shutdown" command
nor its (eventual) replacement.

Detect if the main loop is terminated by an external signal and
in such case execute explicitly the command "shutdown".
Replace with enum the magic numbers assumed by "shutdown_openocd".

Please notice that it's possible to write a custom "shutdown" TCL
proc that does not call the original "shutdown" command. This is
useful, for example, to prevent the user to quit OpenOCD by typing
"shutdown" in the telnet session.
Such case will not prevent OpenOCD to terminate when receiving a
signal; OpenOCD will quit after executing the custom "shutdown"
command.

print the content of IDR register, and the query is only possible

But IDR information is already printed by the dedicated command
apid, making redundant printing it by apsel too.
Being unable to run apsel during initialization, makes also apcsw
command (that depends on apsel) not usable in such phase.

Modify the command apsel to only set the current AP, without making
any transfer to the (possibly not initialized yet) DAP. When run
without parameters, just print the current AP number.

There is no reason to restrict the command "cortex_a dacrfixup"
to the EXEC phase only.
Change the command mode to ANY so the command can be used in

* target/cortex_m: restore C_MASKINTS after reset

The cortex_m maskisr user-facing setting is not changed across a target
reset. However, the in-core C_MASKINTS bit was always cleared as part of
reset processing, meaning that a cortex_m maskisr on setting would not
be respected after a reset. Set C_MASKINTS based on the user-facing
setting value rather than always clearing it after reset.

Bas Vermeulen ada631cc5f target aarch64: rework memory read/write to use 8/16/32 bit operations
The existing code only used Memory Access mode to read memory,
which uses 32 bit operations only.
Rework the code to check the alignment/size of the read/write operation,
and use the Memory Access mode to read aligned 32 bit memory.
When using unaligned access, or 8 or 16 bit reads, use LDR{BHW} and STR{BHW}
instead.

The exception handling is still the same as it was before (meaning it breaks
when things go wrong), but I can now read an 8 bit register correctly.

Matthias Welwarsky bf1efe05bb aarch64: run control rework
This patch contains a major overhaul of the target run control,
mainly for the sake of satisfying gdbs ideas of how a target
should respond to various control requests for the debugger.

The changes allow gdb a slightly better control on how cores
are stepped: a core can be single-stepped while 
other cores remain halted or continue normal execution 
until the single-stepped core halts again.

Also, on any halting event (user command or breakpoint) the
system is brought into a stable state with all cores halted
before the halt is signaled to the debugger.

This patch also transitions the target code to make use of the
new CTI abstraction instead of accessing CTI registers directly.

Matthias Welwarsky ccb1199d49 aarch64: enable aarch32 debugging with arm gdb
When a PE is in Aarch32 state and gdb asks for a target description,
provide a register view compatible with the "org.gnu.gdb.arm.core"
feature. Only current-mode registers are exported, banked registers are
not visible.

Matthias Welwarsky c30f8d6a07 aarch64: handle exceptions taken in debug state
When an armv8-a PE causes an exception while halted, e.g. by performing
a prohibited memory or register access, its state is affected in the
same way as if it was running. That means, a number of registers is
overwritten (notably DLR and DSPSR, but also others) and also
potentially the exception level and therefore also the PE state can
change. This state must be restored before resuming normal operation.

This is done by marking the relevant cached registers "dirty" so that
they are written back before resume.

Matthias Welwarsky 946958cb72 aarch64: fix mode switching
DCPS only allows to enter higher ELs, for lower ELs you need to
use DRPS. Also, of course the encoding differs between A64 and T32.
Both DCPS and DRPS also clobber DLR and DSPSR, which then need to be
restored on resume.

Matthias Welwarsky 79c4c22e15 aarch64: register access rewrite
All register access is now performed through common read/write
functions, which delegate the actual register access to the
armv8_common object. armv8_common contains function pointers
to direct read and write requests to the respective low-level
functions for each PE state.

The respective read/write functions are selected on debug state
entry.

At the same time, T32 opcodes are now formatted for ITR in
dpmv8_exec_opcode() and the T32_FMTITR macro is removed from global
visibility.

Matthias Welwarsky b430d0a152 aarch64: disable interrupts when stepping [WIP]
On live hardware, interrupts will happen while the core is
held for stepping. The next step will most of the time execute an
interrupt service instead of the next line of code, which is not
what you expect. Disable interrupts through DSCR before resuming
for a step, and re-enable them again after the step happened.

This should be made configurable, like on cortex_a target.
