[PATCH 0/2] arm: add a /proc/cpuinfo platform extension

[H Hartley Sweeten]

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 1/2 adds the necessary core support to allow a platform
specific callback to dump this information.

Patch 2/2 adds a callback to mach-ep93xx and hooks up all the
edb93xx platforms.
