[PATCH] ARM: kconfig: allow PCI support to be selected with ARCH_MULTIPLATFORM

When targetting ARCH_MULTIPLATFORM, we may include support for SoCs with
PCI-capable devices (e.g. mach-virt with virtio-pci).

This patch allows PCI support to be selected for these SoCs by selecting
CONFIG_MIGHT_HAVE_PCI when CONFIG_ARCH_MULTIPLATFORM=y and removes the
individual selections from multi-platform enabled SoCs.

Hi Arnd, Olof, Kevin,

Please can you take this patch via the arm-soc tree for 3.16? It doesn't
really fit with the generic PCI host driver that I'll send via Bjorn and
it seems OTT to send you a pull request containing just this patch.

Cheers,

Will
