ARM: prevent misaligned array inits
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. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net> [trini: Switch to usign call cc-option for -mno-unaligned-access as Albert had done previously as that's really correct] Signed-off-by: Tom Rini <trini@ti.com>
