[RFC PATCH 00/11] kvm tools: allow ioport emulation to be used on ARM

[Will Deacon <will.deacon@arm.com>]

Hi guys,

This RFC series does a number of things, but the main goal is to allow
re-use of the emulation code under hw/ on architectures other than x86.
It also comes about after discussions concerning virtio-console for
earlyprintk:

  http://lists.infradead.org/pipermail/linux-arm-kernel/2013-April/165605.html

The first 5 patches in this series allow the 8250 emulation to be used
for earlyprintk (i.e. output only) on aarch64 platforms. The remaining 7
patches generalise this to potentially any ioport devices, with DT node
generation and interrupt routing.

All comments welcome,

Will
