Because the stack pointer is already set in arch/arm/lib/crt0.S,
we do not need to set it in arch/arm/lib/spl.c.

The subject prefix "[PATCH 2/8]" is wrong.
(My misoperation of git format-patch)

This is composed of only one patch file.


I have just post the correct version.


Please delete this thread or just ignore.
Sorry for noise.
