Yes, I guess we can do that too. FWIW, almost all the problems
were uses of cpu_is_omap*(), omap_read*() and omap_write*().

There are quite a lot of them overall, but at least they are
easy to grep for, and there should be an obvious fix for each
of them, following what you did on OMAP2 a couple of years ago.

Ok, I've put this patch in my randconfig build setup to replace
my older patch, let's see if there are still some corner cases
left. So far, everything looks good (50 random mach-omap1 builds
done). Can you send an updated pull request with the fix folded in?
