Best would be to move to the Linux GPIO API for PPC4xx in U-Boot now then. This has been discussed before on the list. And is on my list of open tasks. But it will have to wait a few more weeks I'm afraid. Perhaps you have some spare cycles left to migrate the current GPIO API to the Linux one? See Blackfin arch as an example.
