* Make sure Block Lock Bits get cleared in R360MPI flash driver

Browse Source 
* 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

@ -789,6 +789,18 @@ The following options need to be configured:
Normally display is black on white background; define
CFG_WHITE_ON_BLACK to get it inverted.
- Spash Screen Support: CONFIG_SPLASH_SCREEN
If this option is set, the environment is checked for
a variable "splashimage". If found, the usual display
of logo, copyright and system information on the LCD
is supressed and the BMP image at the address
specified in "splashimage" is loaded instead. The
console is redirected to the "nulldev", too. This
allows for a "silent" boot where a splash screen is
loaded very quickly after power-on.
- Ethernet address:
CONFIG_ETHADDR
CONFIG_ETH2ADDR
