* ARM: prevent misaligned array initsAlbert ARIBAUD2012-10-15-5/+8
| | | | | | | | | | | | | | 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>
* arm: armv7: omap3: Fix restore sequence in lowlevel_initAlbert ARIBAUD2012-10-08-5/+4
| | | | | | | | | | | The restore sequence in lowlevel_init was in the wrong order, causing lr to lose its original value and be set equal to ip instead. Also, its use of the stack clashes with that of s_init, so move the s_init call after the restore and turn it into a tail-optimized branch.

* arm: rmobile: bugfix: wrong register saving in lowlevel_initTetsuyuki Kobayashi2012-10-08-11/+1
| | | | | | | | lowlevel_init() of rmobile badly assumed that ip register holds return address. The commit "63ee53a7 armv7 cpu_init_crit: Simplify code" breaks this assumption. This patch removes this bad assumption and simplify code. Signed-off-by: Tetsuyuki Kobayashi <koba@kmckk.co.jp>
* arm: armv7: temporarily set -mno-unaligned-accessAlbert ARIBAUD2012-10-05-0/+2
| | | | | | | | | This patch aims at ensuring that the 2012.10 release works out-of-the-box on as many targets as possible, by reinstating commit 5347560f5427bcdd48a563b62180481606ac8044, which adds option -mno-unaligned-access to armv7 builds. This patch will be overriden immediately after release of 2012.10.

* ARM: increase lmb stack space reservation to 4KBRob Herring2012-10-04-2/+2
| | | | | | | | | | The bootm initrd image copy to ram can collide with the stack in cases where the print buffer size is large (i.e. 1K). The result is intermittent initrd decompression errors depending on the initrd size MOD 4KB since the initrd start address is 4KB aligned.
