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
