Hi Jeremy,

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.
Very nice! Thanks for getting to the bottom of this.
However, looking at the patches, they are riddled with coding style violations. I am usually less strict than Leif when it comes to upholding those, but these patches really need to be cleaned up to be considered for merging.
When combined with the ARM/PCI dma lib changes this allows us to relax the IO alignment requirement that caused grub failures.
What changes are you referring to here?
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.
