Is this because of some bug in kirkwood soc or missing code in
sata_mv.c?
According to the functional specification of kirkwood there is a
PhyShutdown bit in it's registers. Dove also has this register bit.
Up to now it looks like the SATA PHY can only be disabled in code,
but there should be an phy_enable, too.
What repository your kernel is based on?
