2014-02-26	arm: Switch to -mno-unaligned-access when supported by the compiler	Tom Rini
	When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.

2012-10-15	ARM: prevent misaligned array inits	Albert ARIBAUD
	Under option -munaligned-access, gcc can perform local char or 16-bit array initializations using misaligned native accesses which will throw a data abort exception. Fix files where these array initializations were unneeded, and for files known to contain such initializations, enforce gcc option -mno-unaligned-access.
