Ah OK it's changed here.. Sorry I was looking at the older
version.

You should probably add a function for setting omap_control_base
separately from *set_globals* in arch/arm/mach-omap2/common.c.
That way it's initialized early for id.c, and you can initialize
everything else later as regular device drivers.
FYI, we want to initialize as much as possible late so we have
proper debugging console set up in case things go wrong.

Tony
