This option enables support for running as a QEMU guest using
QEMU's generic e500 machine. This is not required if you're
using a QEMU machine that targets a specific board, such as
mpc8544ds.
Unlike most e500 boards that target a specific CPU, this
platform works with any e500-family CPU that QEMU supports.
Thus, you'll need to make sure CONFIG_PPC_E500MC is set or
unset based on the emulated CPU (or actual host CPU in the case
of KVM).
