[PATCH v2 0/7] ATAPI support on SiI SATA adapter

[PATCH v2 0/7] ATAPI support on SiI SATA adapter

[Jeremy Linton]

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.

V1->V2:
  Formatting corrections per Ard's comments and Daniil's
  updated patch checker.

[PATCH v2 2/7] MdePkg IndustryStandard/Scsi.h: Add sense code macro

[Jeremy Linton]

Add some definitions to mask the sense key from sense data,
and check the validity of the returned sense data.

[PATCH v2 3/7] EmbeddedPkg: SiI3132: Add ScsiProtocol callbacks

[Jeremy Linton]

Create a new module that adds the callbacks to support
the EFI SCSI pass-through protocol. These callbacks
wrap around the existing ATA pass-through callbacks.
In particular the SCSI command submission routine takes
the SCSI command and wraps it with an SATA FIS and
sets the protocol to ATAPI. It then forwards the FIS to
a new routine we will break out of the ATA pass-through
callback that manages the FIS submission to the adapter.

[PATCH v2 5/7] EmbeddedPkg: SiI3132: Break out FIS command submission

[Jeremy Linton]

The existing ATA pass-through routine builds the FIS and handles
submission to the hardware. Break out the FIS submission part
so that it can be utilized by the SCSI pass-through. Also,
tighten up the error handling a bit. Starting with removal
of the ASSERTs on errors. ATAPI like SCSI uses check
conditions to indicate device state changes. So these error
paths can get exercised on CD disk change/etc. Further
we want the clamp the timeouts within a range rather than
spinning forever if the port fails to become ready.

[PATCH v2 6/7] EmbeddedPkg: SiI3132: Cleanup device node creation

[Jeremy Linton]

There can be either ATA or ATAPI devices connected to
each SATA port. We want to detect if the device is ATA
and create a SATA_DP path or a SCSI_DP for ATAPI devices.

[PATCH v2 7/7] EmbeddedPkg: SiI3132: Enable SCSI pass-through protocol

[Jeremy Linton]

Now that everything is in place, lets export the protocol,
build the module, and remove the ATAPI unsupported flags.
Now when we detect an ATAPI device on a port we flag it
as such.

[Jeremy Linton]

Sorry about the noise.

Thanks,
