Hello Vitaly,
If my understanding is correct, this driver (SataControllerDxe) and the
AtaAtapiPassThru driver are written for non-RAID case only.
Both drivers (especially AtaAtapiPassThru) do not distinguish logic/physical
SCSI channels, which I think only works for the non-RAID case. I am not sure if
this patch series will have an impact to existing RAID drivers.
Best Regards,
Hao Wu
