/** @file
Cirrus Logic 5430 Controller Driver.
This driver is a sample implementation of the UGA Draw and Graphics Output
Protocols for the Cirrus Logic 5430 family of PCI video controllers.
This driver is only usable in the EFI pre-boot environment.
This sample is intended to show how the UGA Draw and Graphics output Protocol
is able to function.
The UGA I/O Protocol is not implemented in this sample.
A fully compliant EFI UGA driver requires both
the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's
documentation on UGA for details on how to write a UGA driver that is able
to function both in the EFI pre-boot environment and from the OS runtime.

# Cirrus Logic 5430 Controller Driver.This driver is a sample implementation
# of the UGA Draw Protocol for the Cirrus Logic 5430 family of PCI video controllers.
# This driver is only usable in the EFI pre-boot environment. This sample is
# intended to show how the UGA Draw Protocol is able to function. The UGA I/O
# Protocol is not implemented in this sample. A fully compliant EFI UGA driver
# requires both the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's
# documentation on UGA for details on how to write a UGA driver that is able
# to function both in the EFI pre-boot environment and from the OS runtime.

For now, AtapiPassThru driver in this package is to test Scsi Bus support:
ScsiBus driver should support both/either ScsiPassThru and ExtScsiPassThru
installed on a controller handle.
AtapiPassThru driver in this package can selectively produce ScsiPassThru
and/or ExtScsiPassThru protocol based on feature flags of PcdSupportScsiPassThru
and PcdExtScsiPassThru.
