revision:\n- the assist registers contain the SoC's \"major version\" which encodes\n the SoC generation and part number. this is available on Meson6,\n Meson8 and Meson8b SoCs.\n- the bootrom register contains at least the SoCs \"misc version\". this\n is avilable on Meson6, Meson8 and Meson8b\n- the analog top registers contain information about the SoC revision.\n this is only available on Meson8 and Meson8b\n\nNot much else is currently known about these registers.\n\nSigned-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>\n---\n
