Andreas Färber 81631e49a6 contrib/loaders: Enforce Little Endian ARM machine code
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.

Tomas Vanek 0e95629eb1 flash Kinetis: Implement flash protection setting
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.

Tomas Vanek a46eb1f082 flash Kinetis: refactoring ftfx commands and numerous minor changes
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.

Tomas Vanek 77a1c01ccb flash/nor: implement protection blocks of different size than erase sector
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.

Tomas Vanek 77478eb0f5 flash Kinetis: dynamic status detection before starting mass_erase
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.

Tomas Vanek 6d5b4d709c flash Kinetis: Detect RESET/WDOG loop, fix detection of secured MCU
Kinetis driver checks MDM STAT register to detect secured state of MCU.
Original version often reported a blank device as secured one.
Change #3010 has not fixed all false reports.
After changes in arm_adi_v5 infrastructure secured devices was not detected
at all.

New algorithm uses multiple MDM STAT reads and counts MDM_STAT_SYSSEC and
MDM_STAT_FREADY bits. Both secured MCU and MCU locked-up in RESET/WDOG loop
are detected reliably.

Detection is run in both kx.cfg and klx.cfg from examine-start event,
not examine-end as before. Event is configured only for non hla adapter.

Minor fix in klx.cfg: commented out adapter_khz 24000 in reset-init.
Such frequency is not supported in VLPR CPU mode and with JTAG.
