The ARM Juno boards can be used as somewhat decent machines to run off-the-shelf distributions, with USB, SATA, GBit Ethernet and 8GB of DRAM. With stable DTs in the board's NOR flash this would work really nicely, however the default boot command is to fetch a kernel and an initrd from the on-board NOR flash, which sounds somewhat embedded. Include the config_distro_bootcmd.h header and define the available devices (starting with USB, to catch USB installer sticks) to make distributions and UEFI work out of the box. The NOR flash kernel functionality is still preserved as the last resort, should all other methods fail.
