* 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
