Is it possible to let patch 1~3 go through PCI tree and patch 4~5 go through MIPS tree? Thanks. v6: Drop first the patch of previous versions. Driver code clean-ups according to rob's suggestion. It looks like I had a wrong impression on generic IO port handeling and now the issue has been fixed, I implemented PCI_IOBASE for MIPS[1]. Now the address is uniform here.
