Benjamin Barenblat 82ef8ada82 src/commonlib/lz4_wrapper: Correct inline asm for unaligned 64-bit copy
Rewrite inline assembly for ARMv7+ to correctly annotate inputs and
outputs.  On ARM GCC 6.1.1, this causes assembly output to change from
the incorrect

	@ r0 is allocated to hold dst and x0
	@ r1 is allocated to hold src and x1
	ldr r0, [r1]		@ clobbers dst!
	ldr r1, [r1, #4]
	str r0, [r0]
	str r1, [r0, #4]

to the correct

	@ r0 is allocated to hold dst
	@ r1 is allocated to hold src and x1
	@ r3 is allocated to hold x0
	ldr r3, [r1]
	ldr r1, [r1, #4]
	str r3, [r0]
	str r1, [r0, #4]

Also modify checkpatch.pl to ignore spaces before opening brackets when
used in inline assembly.

Stefan Reinauer 59c2c8b079 checkpatch: fine tune checks
Fine tune the following two checks:

- Check for incorrect file permissions
  This one had a linux path hard coded, so it would choke on
  some commits unnecessarily.
- FILE_PATH_CHANGES seems to not be working correctly. It will
  choke on added / deleted files even if the MAINTAINERS file
  is touched. Hence, switch from WARN to CHK (as WARN currently
  blocks commits as well)

Stefan Reinauer c5269007c9 checkpatch: fix tree recognition
With the recent rename of documentation -> Documentation, the
checkpatch.pl script broke. Fix the tree check, and change the
user visible output of "kernel" to coreboot.

Stefan Reinauer 44d0fd9841 Add Linux kernel's checkpatch.pl script
Carefully staging to enable checkpatch for coreboot contributions.

The biggest offender of the rules enforced by checkpatch I have found so
far is ... Oh, you guessed it? It's checkpatch itself.
