Description
The ARM PrimeCell PL110 Color LCD Controller is a AMBA compliant module that provides LCD display support for both TFT and STN displays in a variety of configurations.
While the controller supports TFT displays it differs from other TFT display controllers because it has a DMA interface to system memory rather than using SPI or other serial transfer protocols.
Currently this driver only supports the setup required for the QEMU VersatilePB target however it is possible to support additional configurations by adding more variations of the PL110FramebufferCreate functions (eg PL110FramebufferCreateSTN etc).
Note: The driver does not include support for FRAMEBUFFER_FLAG_SYNC as the QEMU emulation of the device does not provide interrupt support at present.

PL110 functions
function PL110FramebufferCreateVGA(Address:LongWord; const Name:String; Rotation,Width,Height,Depth:LongWord):PFramebufferDevice;
Description: Create, register and allocate a new PL110 Framebuffer device which can be accessed using the framebuffer API
| Address | The address of the PL110 registers |
