The LWMON project uses a frozen version of the Linux kernel code, so
we didn't port their board to a more recent kernel version yet.
Please see arch/ppc/8xx_io/lwmon_kbd.c in the (old ) linux-2.4 kernel
tree.

Then you will probably use something similar to the standard PC
keyboard code; feel free to peek into drivers/ps2*.c in the U-Boot
sources.

I don't know this hardware either.

You are welcome.
