[U-Boot] [PATCH] Canyonlands SATA harddisk driver

Hello,

The SATA harddisk driver is based on the Linux kernel source code.
Therefore, the software structure is the same structure as the Linux
kernel driver.

DMA function was scheduled to be developed as my schedule.
However, the development of the DMA function is discontinued once now.
The structure of the register that controls DMA has not been used any longer.
I will e-mail the source code ( removed the struct of DMA register ) later.

Regards,
Kazuaki Ichinohe
