Now you can attach with gdb, and it'll attempt to read a register. That
will fail because the core won't clear debug interrupt. Adding nops
doesn't help this time.
arm-none-eabi target triplet defaults to Little Endian, and so far any
submitted machine code snippets have been verified to be Little Endian.
However a user might override [ARM_]CROSS_COMPILE with an armeb toolchain,
potentially resulting in invalid machine code.
Let's be safe and enforce Little Endian mode for assembler and compiler.

Kinetis family employs strange concept of Flash Configuration Field at
address 0x400 of program flash. Writing incorrect data to FCF may
permanently lock the device.
The change introduces 'kinetis fcf_source protection' mode. In this mode
write of flash image data to FCF is prevented. FCF data build from
protection (set by 'flash protect' command) are written instead.
FCF data are written also just after erase of relevant sector. It
protects device from locking security by reset or power cycle after erase.
prot_blocks array is used as protection blocks have bigger size than sectors.
Alignment and padding programming sections is rewritten to fix
writing with not section boundary aligned begin.

Add kinetis_ftfx_decode_error() to show flash error type in human
readable message.
Add kinetis_ftfx_prepare() to prepare flash module just once in
command (not each time kinetis_ftfx_command() is called).
Change target_read/write_memory() to target_read/write_u8/32().
Make ftfx_fstat parameter of kinetis_ftfx_command() optional.
Longword flash write:
Fix huge memory leak after write of unaligned block.
Check flash address alignment properly.
Do not fill whole padding buffer but its end after original data.
Remove duplicite padding.

Originally flash/nor infrastructure assumed protection blocks identical
to erase sectors. This assumption is not valid for many flash types.
Driver code fixed the problem either by increasing sector size to
size of protection block or by defining more protection block than
really existed in device. Both cases had drawbacks.
The change retains compatibility with the old driver.
Updated driver can set protection blocks table independent
of sector table.

The change prevents starting mass_erase in unstable state of MCU
(RESET/WDOG loop).
mass_erase of secured MCU using manual reset button is supported.
Timeouts are measured by timeval_ms() instead of iteration count.
mass_erase timeout prolonged to 16 seconds because aborting
mass_erase in progress (deasserting reset) leaves the device
in security locked state.
