'''ARM PrimeCell PL110 Color LCD Controller Driver unit'''

The ARM PrimeCell PL110 Color LCD Controller is an 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.
