Already done - commit 48539e37c38c4f6ff78aba6134de2ae3cc3b5dab in the
85xx tree does a global sweep of the board file, and commit
ac2cb674bd5dd1405ea0413adb71c253481d9a00 (also in 85xx) is an updated
version of this commit that uses the I/O accessors, and also the new
PCI helper functions that Kumar requested.

Thanks,
Paul.
