This is the driver for the Toshiba TX4939 SoC ATA controller.

This controller has standard ATA taskfile registers and DMA
command/status registers, but the register layout is swapped on big
endian.  There are some other endian issue and some special registers
which requires many custom dma_ops/port_ops routines.

This patch is against linux-next 20080916.

Changes since v1:
* rework IO accessors
* rework pio/dma timing setup
* use ide_get_pair_dev
* do not do ATA hard reset
* and so on  (Many thanks to Sergei)

Sergei, are you OK with this version?

  I didn't have tome to look at it.

WBR, Sergei
