Without the change cortex_m_debug_entry() reads all registers
calling cortex_m_load_core_reg_u32() for each register with
a poor usage of JTAG/SWD queue.
It is time consuming, especially on an USB FS based adapter.
Moreover if target_request debugmsgs are enabled, DCB_DCRDR
is saved and restored on each register read.
This change introduces cortex_m_fast_read_all_regs()
which queues all register reads and a single dap_run() transaction
does all work.
cortex_m_fast_read_all_regs() reads all registers unconditionally
regardless register cache is valid or not. This is a difference
from the original cortex_m_debug_entry() code.

Added checking of DHCSR.S_REGRDY flag. If "not ready" is seen,

register read method cortex_m_slow_read_all_regs() is used

xPSR.T sets the processor to Thumb mode when set to 1. ARMv7-M only
supports execution of Thumb instructions, so it must always be set to 1.
If xPSR.T is set to 0 on armv7m, a usage fault is generated when a
instruction execution is attempted.
On armv7m, issuing a reset causes the vector table to be examined. PC
and xPSR.T are loaded from the vector table at byte offset 4. xPSR.T is
taken from the least significant bit this value, PC from the remaining
bits. This occurs even with `reset halt`, as the reset itself causes
this load to occur without the execution of any instructions.
As a result of this, following a reset with a "bad" value programmed in
the vector table, openocd would be unable to run algorithms on the
target, as running them would immediately result in a usage fault due to
xPSR.T being unset (0).
Allow algorithms to run regardless of the content of the vector table by
explicitly setting xPSR so that xPSR.T=1 prior to executing an
algorithm. One can think of this as openocd more closely emulating a
reset or branch instruction in executing it's algorithms.

The new common semihosting code introduced a bug,
in certain conditions target->semihosting was
used without semihosting being initialised.
The solution was to explicitly test for
target->semihosting before dereferencing it.

In 2016, ARM released the second edition of the semihosting specs
("Semihosting for AArch32 and AArch64"), adding support for 64-bits.
To ease the reuse of the semihosting logic for other platforms
(like RISC-V), the semihosting code was isolated from the ARM
target and updated to the latest specs.
The new code is already in use since January (in GNU MCU Eclipse
OpenOCD) and no problems were reported, neither for ARM nor for
RISC-V targets, after more than 7K downloads.
The 2 new files were formatted with uncrustify.

Tested on PSoC6 (Cortex-M0+ core), onboard KitProg2 in CMSIS-DAP mode,
adapter_khz=1000.
Plain read:
flash read_bank 0 /dev/null
takes 48 seconds.
erase_check without this change:
flash erase_check 0
takes horrible 149 seconds!!
And the same command with the change applied takes 1.8 seconds.
Quite a difference.
Remove the erase-value=0 version of algorithm as the new one can check
for any value.
If the target is an insane slow clocked CPU (under 1MHz) algo
timeouts. Blocks checked so far are returned and the next call
uses increased timeout.

'flash erase_check' command runs a check algorithm on a target
if possible. The algorithm is run repeatedly for each flash sector.
Unfortunately every start and stop of the algorithm impose not negligible
overhead.
In practice it means checking is faster than plain read only for
sectors of size approx 4 kByte or bigger. And checking sectors
as short as 512 bytes runs approx 4 times slower than plain read.
The patch changes API call target_blank_check_memory() and related
to take an array of sectors (or arbitrary memory blocks).
Changes in target-specific checking routines are kept minimal.
They use only the first block from the array and process it by
the unchanged algorithm.
default_flash_blank_check() routine repeats target_blank_check_memory()
until all blocks are checked, so it works with both multi-block
and single-block based checkers.

Define a target_addr_t type to support 32-bit and 64-bit addresses at
the same time. Also define matching TARGET_PRI*ADDR format macros as
well as a convenient TARGET_ADDR_FMT.
In targets that are 32-bit (avr32, nds32, arm7/9/11, fm4, xmc1000)
be least invasive by leaving the formatting unchanged apart from the
type;
for generic code adopt TARGET_ADDR_FMT as unified address format.
Don't silently change gdb formatting here, leave that to later.
Add COMMAND_PARSE_ADDRESS() macro to abstract the address type.
Implement it using its own parse_target_addr() function, in the hopes
of catching pointer type mismatches better.
Add '--disable-target64' configure option to revert to previous 32-bit
target address behavior.

This patch adds support for bridging semihosting to GDB's File-I/O
remote protocol extension. For the most part operations match up 1:1,
however some require a working area to complete successfully, namely
operations that devolve to read, stat, and gettimeofday.
A new command was added to enable support for fileio named `arm
semihosting_fileio`, which ensures that the default behavior remains
intact for those that prefer it.
Finally, redundant logging was removed from the target_arch_state
function; this permits ARM targets to quiesce log output when polling
for a fileio reply. This prevents filling the logs with halt/resume
messages when using semihosting fileio.

struct flash_driver has a default_padded_value field that is similar,
but it can be changed by the user for the specific purpose of padding.
Add a new erased_value field and initialize it for all targets,
particularly stm32lx, xmc4xxx and virtual.
Use this value in core.c:default_flash_mem_blank_check(), the slow path.
Extend the target API to pass erased_value down to target code.
Adding an argument ensures that we catch all callers.
This allows us to merge xmc4xxx.c:xmc4xxx_blank_check_memory() into
armv7m:armv7m_blank_check_memory().
It further allows us to use default_flash_blank_check() in place of
xmc4xxx.c:xmc4xxx_flash_blank_check(), adding a potential slow path
fallback, as well as stm32lx:stm32lx_erase_check(), adding the potential
armv7m fast path with fallback to default_flash_mem_blank_check().
Fix a mips32 code comment while at it (zeroed -> erased).
The armv4_5 and mips32 target implementations will now error out if an
erase value other than 0xff is used, causing default_flash_blank_check()
to fall back to the default_flank_mem_blank_check() slow path.

This patch adds the fpv4-sp-d16 registers to the armv7m register set.
The work is inspired by Mathias K but takes a different approach:
instead of having both double and single presicion registers in the
cache this patch works only with the doubles and counts on GDB to
split the data in halves whenever needed.
Tested with HLA only (on an STM32F334 disco board).
Currently this patch makes all ARMv7-M targets report an FPU-enabled
target description to GDB. It shouldn't harm if the user is not trying
to access non-existing FPU. However, the plan is to make this depend
on actual FPU presence later.
