+ 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.
