Cleaned up AMD Au1200 IDE driver:
- converted to platform bus - removed pci dependencies - removed virt_to_phys/phys_to_virt calls System now can root off of a disk. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> diff --git a/Documentation/mips/AU1xxx_IDE.README b/Documentation/mips/AU1xxx_IDE.README new file mode 100644
