    Hi Alexev,

    I'm aware Amlogic also runs their kernel as 32bit to gain a few kbytes
    of memory, but those processors are ARMv8 and the arm64 arch code
    has been designed for those CPUs.

    So far I didn't find a single good reason to add 32bit support for
    ARMv8 Amlogic based SoCs, if you have a solid reason please share.

    And as Krzysztof stated, the support is incomplete and cannot work
    without a dts file.
