-U-Boot vcxk video controller driver
-======================================
-
-By defining CONFIG_VIDEO_VCXK this driver can be used with VC2K, VC4K and
-VC8K devices on following boards:
-
-board           | ARCH          | Vendor
------------------------------------------------------------------------
-EB+CPU5282-T1   | MCF5282       | BuS Elektronik GmbH & Co. KG

-ZLSA            | AT91RM9200    | Ruf Telematik AG
-
-Driver configuration
---------------------
-
-The driver needs some defines to describe the target hardware:
-
-CONFIG_SYS_VCXK_BASE
-
-	base address of VCxK hardware memory
-
-CONFIG_SYS_VCXK_DEFAULT_LINEALIGN
-
-	defines the physical alignment of a pixel row
-
-CONFIG_SYS_VCXK_DOUBLEBUFFERED
-
-	some boards that use vcxk prevent read from framebuffer memory.
-	define this option to enable double buffering (needs 16KiB RAM)
-
-CONFIG_SYS_VCXK_<xxxx>_PIN
-
-	defines the number of the I/O line PIN in the port
-	valid values for <xxxx> are:
-
-		ACKNOWLEDGE
-			describes the acknowledge line from vcxk hardware
-
-		ENABLE
-			describes the enable line to vcxk hardware
-
-		INVERT
-			describes the invert line to vcxk hardware
-
-		RESET
-			describes the reset line to vcxk hardware
-
-		REQUEST
-			describes the request line to vcxk hardware
-
-CONFIG_SYS_VCXK_<xxxx>_PORT
-
-	defines the I/O port which is connected with the line
-	for valid values for <xxxx> see CONFIG_SYS_VCXK_<xxxx>_PIN
-
-CONFIG_SYS_VCXK_<xxxx>_DDR
-
-	defines the register which configures the direction
-	for valid values for <xxxx> see CONFIG_SYS_VCXK_<xxxx>_PIN
