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.

On SMP targets, the "target smp" command creates a list of targets
that belong to the SMP cluster. Free this list when a target gets

individually removing targets from the list.

KitProg firmware does not send a zero length packet at the end of the bulk-in
transmission of a length divisible by a bulk packet size. This is inconsistent
with the USB specification and results in jtag_libusb_bulk_read()
waits forever when a transmission of specific size is received.
Limit bulk read size to expected number of bytes for problematic tranfer sizes.
Use 1 second timeout as the last resort.

Avoid ever overflowing the DWT_COMPARATOR array by allocating space for
16 comparators (the field is masked by 0xf).
On a stm32f767zi chip (on a nucleo-767zi board) I've been seeing crashes
with address sanitizer enabled due to its (apparent) 10 present
comparators. This appears to be due to
https://sourceforge.net/p/openocd/tickets/178/.
In non-address sanitizer builds, this would likely cause some random
memory to be written to in some cases. (see above bug for observations).
