Cortex-M target used 'auto_bp_type' mode. The requested type
of breakpoint was ignored and hard (FPB) breakpoints were set in
'code memory area' 0x00000000-0x1fffffff, soft breakpoints were set above
0x20000000.
The code memory area of Cortex-M does not mean the memory is flash and
vice versa. External flash (parallel or QSPI) is usually mapped above
code memory area. Cortex-M7 ITCM RAM is mapped at 0. Kinetis
has a RAM block under 0x20000000 boundary.
Remove 'auto_bp_type' mode, set breakpoints to requested type.
Change 'cortex_m maskisr auto' handling to use a hard temporary
breakpoint everywhere: it can also workaround not working soft breakpoints
on Cortex-M7 with ICache enabled.

Most of flash drivers have to ensure proper flash write block alignment
and padding. As there was no support for it in the flash infrastructure,
each driver does it its own way. Sometimes this part of code is not properly
tested and contains bugs.
flash_write(_unlock) joins all image sections targeted to one flash bank
using padded areas as a glue. This solves alignment problems on section
boundaries but imposes other problems.
Introduce new flash bank parameters write_start_alignment,
write_end_alignment and minimal_write_gap.
New flash drivers can just properly set these values instead of handling
alignment by its own.
Adapt infrastructure (namely flash_write_unlock(), handle_flash_fill_command()
and handle_flash_write_bank_command()) to prepare write data padded
to an alignment required by the flash bank.
Rework flash_write_unlock() to discontinue write block when the gap
between sections is bigger than minimum specified in minimal_write_gap.
minimal_write_gap is set to one sector by default.

erase_check without this change:

And the same command with the change applied takes 1.8 seconds.
Quite a difference.

'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.
