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.

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.

with the USB specification and results in jtag_libusb_bulk_read()

In non-address sanitizer builds, this would likely cause some random

Most Xilinx FPGA devices contain an embedded, unique device identifier.
The identifier is nonvolatile, permanently programmed into the FPGA, and is
unchangeable providing a great serial / tracking number.
This commit adds generic support for reading the Xilinx Spartan 6 and 7
Series (Kintex, Artix, Ultrascale) Device DNA. The code is similar to
the function in fpga/xilinx-xc6s.cfg for Spartan 6 but the register
addresses are different and the logic has been simplified.
The code was not placed in xilinx-xc7.cfg. The approach of defining taps
in the same file as library code to use them is fundamentally broken on
boards that have more than one FPGA or other chips. This commit (like
the addition of support for Xilinx XADC) starts to remedy that by
splitting library code from board-specific fixed definitions.
The support code is sourced in the Kasli and KC705 board support files
as it was tested on these boards.
