I asked about UEFI images on the unofficial solidrun channel [1] recently:

	dsl: btw, https://images.solid-run.com/LX2k/lx2160a_uefi seems
        abandoned. Does anyone know why?

	jnettlet: There is no business use case for it. Since we were
        unable to get patches into mainline linux for the final devices,
        and fixes there was no real reason to move forward with edk2 and
        ACPI since u-boot and device-tree didn't have these limitations

but when I tried one of the FTD-based images from [2], it didn't work
because of a missing PHY for 1 Gbps port. It looks like our "glue" code in
memacphy_fdt/memac_mdio_fdt didn't work in this specific case. FDT
overlay for "fsl_mc: fsl-mc@80c000000" to provide correct values for the
DPMAC corresponding to the 1 Gbps port (dpmac17 IIRC) would be a
workaround for now, but I'll probably have to debug more.
