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 |
||||||
|
EB+MCF-EVB123 | MCF5282 | BuS Elektronik GmbH & Co. KG |
||||||
|
EB+CPUx9K2 | AT91RM9200 | BuS Elektronik GmbH & Co. KG |

|
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 |
||||||
