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 <k...@kmckk.co.jp> --- Hello, Albert Hello, Tom Thank you for merging my patches. I checked current u-boot-master and found kzm9g board fails to boot because bug. This bugfix patch solves it. I think 2012.10 release should have this bugfix.
