+ * from driver/video/chipsfb.c and,

+ * Asiliant 69030 chip (formerly Intel, formerly Chips & Technologies)
+ * Author: apc@agelectronics.co.uk

+ * Note: the data sheets don't seem to be available from Asiliant.
+ * They are available by searching developer.intel.com, but are not otherwise

+ *
+ * This driver should be portable with minimal effort to the 69000 display
