ef14384b68 flash/nor: Use proper data types in driver API
Use 'unsigned int' and 'bool' instead of 'int' where appropriate.
While at it, fix some coding style issues.

No new Clang analyzer warnings.

a7479fa89d Constify struct flash_driver instances
Instances of struct flash_driver are never written to at runtime. For a
small amount of memory saving and also robustness (fewer things for
stray pointer writes to hit), mark them const.

This should allow users to configure flash at >32-bit addresses.

9542cb7c3d flash/nor: consolidate flash protect/protect_check
Make flash_driver methods protect() and protect_check()
optional.

Remove dummy definitions of these methods from the drivers
which do not implement protection handling.

Some drivers did not define protect method. It raised segfault
before this change and now it is handled properly.

Lot of drivers returned ERROR_OK from dummy protect()
- now flash_driver_protect() returns an error if not handled by the driver.

47b8cf8420 target: Add 64-bit target address support
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.

43ff5acd45 flash: New Spansion FM4 flash driver
The Spansion FM4 family of microcontrollers does not offer a way to
identify the chip model nor the flash size, except for Dual Flash vs.
regular layout. Therefore the family is passed as argument and
wildcard-matched - MB9BFx6x and S6E2CC families are supported.

Iterations showed that ...
1) Just doing the flash command sequence from SRAM loader code for each
half-word took 20 minutes for an 8 KB block.
2) Doing the busy-wait in the loader merely reduced the time to 19 minutes.
3) Significant performance gains were achieved by looping in loader code
rather than in OpenOCD and by maximizing the batch size across sectors,
getting us down to ~2 seconds for 8 KB and ~2.5 minutes for 1.1 MB.
(Tested with SK-FM4-176L-S6E2CC-ETH v11, CMSIS-DAP v23.)

gcc, objcopy -Obinary and bin2char.sh are used for automating the
integration of hand-written assembler snippets.
