Subject[RFC PATCH 12/17] powerpc/e500: Separate e500mc CPU table entries from e500v1/e500v2
Date
The e500mc CPUs have a classic FPU and are not compatible with e500v1 or
e500v2. This patch fixes the 32-bit CPU feature tables so that e500mc
entries are not present on e500v1/e500v2 systems and vice versa.
