[U-Boot-Users] [PATCH] Add defines to libata (Take three)

[Dave Liu]

Tor,

I just sent the patch
[PATCH] ata: update the libata.h from ata.h of linux kernel

The patch cover your changes, and is consistent with the latest
ata.h of linux kernel.

Please continue your development with it. Thanks again.

Wolfgang,

Please apply my patch instead of Tor's patch,
I add full set of ata.h of linux to my patch, and add Tor Krill to
Signed-off-by.

Thanks,
Dave
