[PATCH v4 0/8] mips/usb: Add Octeon xHCI USB support

[Stefan Roese]

This patchset adds xHCI USB support for MIPS Octeon. After the xHCI code
has been fixed to support mapped addresses (virt != phys), this patchset
now adds the missing code pieces to enable USB support on Octeon. This
is mainly the USB glue code for Octeon and the MIPS platform specific
changes (cache fixes, platform specific swapping based on address areas,
DT & defcopnfig changes).

Thanks,
Stefan
