[PATCH 1/2] goldfish: definitions for Goldfish on x86 platforms

[Alan Cox <alan@linux.intel.com>]

From: Jun Nakajima <jnakajim@gmail.com>

Based on code by Jun Nakajima but stripped of all the old x86 mach-foo
stuff and turned into a single include file for the Goldfish virtual bus
layer

 shared properly]
