* The PS/2 mux on the BMS2003 board needs 450 ms after power on
before we can access it; add delay in case we are faster (with no CF card inserted) * Cleanup of some init functions * Make sure SCC Ethernet is always stopped by the time we boot Linux to avoid Linux crashes by early packets coming in. * Accelerate flash accesses on LWMON board by using buffered writes
