[Xen-devel] [PATCH v3 09/10] 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.

They are introduced for convience: the user will be able to simply open
the menu and enable the right config for her platform.

Note that this approach has a limitation: it is not possible to "select
a range". In other words, using tiny.config NR_CPUS is set to 4. It is
not possible to increase it to 8 from config RCAR3.

Suggestions are welcome.
