Include support for the ARM(R) RealView Emulation Baseboard platform.
config REALVIEW_MPCORE
bool "Support MPcore tile"
depends on MACH_REALVIEW_EB
help
Enable support for the MPCore tile on the Realview platform.
Since there are device address and interrupt differences, a
kernel built with this option enabled is not compatible with
other tiles.
