Subject: ps3: Disk Storage Driver
From: Geert Uytterhoeven <Geert.Uytterhoeven@xxxxxxxxxxx>
Add a Disk Storage Driver for the PS3:
- Implemented as a block device driver with a dynamic major
- Disk names (and partitions) are of the format ps3d%c(%u)
- Uses software scatter-gather with a 64 KiB bounce buffer as the hypervisor
doesn't support scatter-gather
