Due to lack of kernel driver (on commercial level) or documentation for these gpus, so you need to be both mesa and kernel developer. (Any contribution is gonna require deep knowledge about hardware, domain and time consuming effort.)

not sure we need a different repo, but I would recommend
disabling/removing drivers (gallium and vk) in the amber branch which
are maintained in the main branch
