SubjectRe: [PATCH] Merge the changes from siimage 2.4.22-pre9 to 2.6.0-test2

There is a future proposal to deal with SATAPI devices.
It has to do with the features register having a bit set to define
direction of IO for the PHY.

Expect a proposal to be public in 2-6 months, my best guess.

Obviously I am talking about things that do not exist today again, sorry.
