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