[U-Boot] [PATCH 1/2] Update i386 code (sc520_cdp)

Attempt to bring i386 / sc520 inline with master
Lesson learnt - do not cut and paste into gmail
Eclipse seems to have an issue with the o-umlaut. I've had a search
through the editor preferences but cannot find a way to stop Eclipse
from mangling it. I have completely removed the copyright lines from the
patch as they are, in reality, completely unmodified. I have applied
this patch to a clean pull of master followed by a make sc520_cdp_config
and make all with no patch or compile errors reported.
