[Xen-devel] [PATCH v4 08/10] arm: add QEMU, Rcar3 and MPSoC configs

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Add a "Platform Support" menu with three umbrella kconfig options: QEMU,
RCAR3 and MPSOC. They enable the required options for their hardware
platform.

In the case of the MPSOC that has a platform file under
arch/arm/platforms/, build the file if MPSOC.
