[U-Boot] [PATCH 2/2] update the EB+MCF-EV123 board support

Jens Scharsig
2009-04-22T14:36:24Z

This patch updates the support for EB+MCF-EV123 board
and needs the [PATCH 1/2] new video driver for bus vcxk framebuffers

* remove the board framebuffer driver
* use the common bus_vcxk framebuffer driver
* adds bmp support
* adds splashimage support
* fix serveral cosmetical errors
