[PCS440EP] upgrade the PCS440EP board:
- Show on the Status LEDs, some States of the board. - Get the MAC addresses from the EEProm - use PREBOOT - use the CF on the board. - check the U-Boot image in the Flash with a SHA1 checksum. - use dynamic TLB entries generation for the SDRAM Signed-off-by: Heiko Schocher <hs@denx.de>
