* Make sure Block Lock Bits get cleared in R360MPI flash driver
* MPC823 LCD driver: Fill color map backwards, to allow for steady
display when Linux takes over
* Patch by Erwin Rol, 27 Feb 2003:
Add support for RTEMS (this time for real).
* Add support for "bmp info" and "bmp display" commands to load
bitmap images; this can be used (for example in a "preboot"
command) to display a splash screen very quickly after poweron.
* Add support for 133 MHz clock on INCA-IP board
