[PATCH 0/3] arm: add a /proc/cpuinfo platform extension

Add an optional platform specific extension to /proc/cpuinfo.

Many platforms have custom cpu information that could be exposed
to user space using /proc/cpuinfo.

Patch 1/3 adds the necessary core support to allow a platform
specific callback to dump this information.

Patch 2/3 adds a callback to mach-ep93xx that exposes the two
unique MaverickKey IDs as well as the processor silicon revision
and a number of boot configuration options.

Patch 3/3 hooks up all the ep93xx platforms.
