Subject: * Make sure Block Lock Bits get cleared in R360MPI flash driver
X-Git-Tag: LABEL_2006_03_12_0025~903
X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-uboot.git;a=commitdiff_plain;h=d791b1dc3e64a6a6317293245d884589bc5c6277

* 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

+                If this option is set, the environment is checked for
