Would be cool to test this in CI. Could you add:

  - a defconfig that enables this board (I'd call it mips64_defconfig
    and if another MIPS64 SoC is added, we will add it there, like
    we do now for e.g. multi_v8_defconfig on ARM)

  - a Labgrid env file that configures QEMU appropriately
    See test/mips/qemu-malta_defconfig.yaml for an example

If you like, you can go further and send a patch adding it to
CI's test-labgrid-pytest.yml workflow, but I can do that too.

Cheers,
Ahmad
