The SiI isn't an AHCI compatible adapter so it implements the EFI ATA pass-through protocol directly. This works for fixed hard drives, but not ATAPI attached devices (CDROM, DVDROM, TAPE, etc).
This patch adds read only ATAPI support via the EFI SCSI pass-through protocol, allowing boot from attached CD/DVD. This patch also cleans up, and tweaks recovery paths/etc in the original driver. When combined with the ARM/PCI dma lib changes this allows us to relax the IO alignment requirement that caused grub failures.
Finally, the OpenPlatformPkg/Juno must be updated, with another patch to avoid build breaks now that the SiI has a dependency on the SCSI libraries.
V3->V4 Fixed a bug that in theory kept multiple ATAPI devices from working. More patch formatting fixes per Ard Dropped the sense validation logic, and changes to the Mde header
V2->V3: Send the correct patch, rather than the one I was running the patch checker against.
V1->V2: Formatting corrections per Ard's comments and Daniil's updated patch checker.
