Tim Newsome 1b349df638 WIP hackery. 
Main thing I added is code to output "verilog" for every JTAG op we do,
so we can run the same thing in simulation.

Tim Newsome 84944ded87 Fix up some register stuff. 
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.

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.
