OpenWrt support for Espressobin Ultra

Just got my hands on one of these. Looking at the existing targets the Espressobinv7-emmc target probably includes most if not all of the same hardware (cpu, ram, switch) but the patch seems to indicate it still depends on micro-sd for booting

    This commit adds support for different iterations of ESPRESSObin.
    The added variants are:

    ESPRESSObin with soldered eMMC,

    ESPRESSObin V7, compared to V5 some passive elements changed and ethernet
    ports labels positions have been reversed,

    ESPRESSObin V7 with soldered eMMC.

    Please refer to:

    for instruction how to boot OpenWrt image placed on SD card. It is
    advised for owners of V5 and previous with bootloader based on U-Boot
    2015.01, to upgrade the latest version available at:

The ultra does not have a microsd card slot so booting from the emmc is mandatory. I'm tempted to just try writing the sd-card image using dd and see what happens.
