[PATCH] ppc32: Add support for Freescale e200 (Book-E) core
The e200 core is a Book-E core (similar to e500) that has a unified L1 cache
and is not cache coherent on the bus. The e200 core also adds a separate
exception level for debug exceptions. Part of this patch helps to cleanup a
few cases that are true for all Freescale Book-E parts, not just e500.
