Both of these are defined by the lines which resemble this:
#define CONFIG_BOOTCOMMAND "mmcinit; " \
"fatload mmc 0 a0000000 init.scr ; " \
"autoscr a0000000 ; "

loader with support for USB and network boot, including BOOTP/DHCP,
and NFS mounting support. Please refer to the Das U-Boot website for
details.
