Please use __le* types for all hardware data structures and use sparse
to verify all your endianess handling is correct.
I have preliminary endianness annotations for that puppy; FWIW, a part of
it consists of _removing_ __le.  Folks, readl() returns host-endian and
writel() takes host-endian as argument.  They do conversions themselves.
One needs fixed-endian types in data structures shared with device - i.e.
anything in ioremapped area or dma'd to/from device.
