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

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
