Re: [coreboot] patch: resource map proposal.

[ron minnich]

With a bug fix from peter and a suggest change by Carl-Daniel

Resource map and a way to use the pci config stuff from stage 1, done in
a way that will work in stage 2 (but only for systems that use type 1
config cycles; will fail for type MEM config cycles).

We need to rethink the PCI config stuff per Stepan's comment, in part
because the device tree now includes things that are NOT PCI devices.
Stepan's suggestion, to make the functions take busdevfn as the
parameter, makes a lot of sense.

Committed revision 720.
