* Patches by Udi Finkelstein, 2 June 2003:
- Added support for custom keyboards, initialized by defining a
board-specific drv_keyboard_init as well as defining CONFIG_KEYBOARD .
- Added support for the RBC823 board.
- cpu/mpc8xx/lcd.c now automatically calculates the
Horizontal Pixel Count field.
* Fix alignment problem in BOOTP (dhcp_leasetime option)
[pointed out by Nicolas Lacressonnière, 2 Jun 2003]
* Patch by Mark Rakes, 14 May 2003:
add support for Intel e1000 gig cards.
* Patch by Nye Liu, 3 Jun 2003:
fix critical typo in MAMR definition (include/mpc8xx.h)
* Fix requirement to align U-Boot image on 16 kB boundaries on PPC.
* Patch by Klaus Heydeck, 2 Jun 2003
