Module Name:
pxdisp.c
Abstract:
This file contains all the VGA-specific definitions. This
is meant to be included by all modules that implement
VGA support in the HAL. At this time, that includes pxs3.c
and pxwd.c. It does not include pxp91.c or pxbbl.c because
these video devices don't map VGA registers.
