uboot is a universal bootloader.

You can run distroboot by running run distro_bootcmd. It will boot the first available target it finds:

• mmc1
• usb0
• dhcp

Note that all it does it run the associated boot commands bootcmd_<target> in order. The targets are defined in the boot_targets environment variable.
