    uboot-envtools: mvebu: fix config for mainline u-boot
    
    Mainline u-boot dynamically passes the mtd partitions via devicetree:
    $ cat /proc/mtd
    dev:    size   erasesize  name
    mtd0: 003f0000 00001000 "firmware"
    mtd1: 00010000 00001000 "u-boot-env"
    
    Add support for this setup.
