* 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 Minor changes for KUP4K configuration
