Well, if it is *SoC* specific, then it is not *arch* specific, so yes,
the name should be changed. Now, we don't really have a concept of
'SoC-specific' in U-Boot, so board-specific, as suggested by Simon, is
the 'next not-too-worst thing'.

Still, don't rush to provide a new patch. According to Simon, the Linux
panic was solved and might just not have hit mainline yet; if that is
confirmed, then renaming arch_cleanup_before_linux() becomes moot.

Amicalement,
