[PATCH] Framebuffer driver for Arc LCD board

Add support for the Arc monochrome LCD board.

The board uses KS108 controllers to drive individual 64x64 LCD matrices.
The board can be paneled in a variety of setups such as 2x1=128x64,
4x4=256x256 and so on.  The board/host interface is through GPIO.

+          is based on the KS-108 lcd controller and is typically a matrix
+          of 2*n chips. This driver was tested with a 128x64 panel. This
+          driver supports it for use with x86 SBCs through a 16 bit GPIO
+          interface (8 bit data, 8 bit control). If you anticpate using
+          this driver, say Y or M; otherwise say N. You must specify the
+          GPIO IO address to be used for setting control and data.
