HiSilicon Kirin

Family of Huawei-manufactured chips, included in almost every Huawei ARM device. Very minimal mainline support is present, but often the proprietary nature of these SoCs makes it difficult to run anything beyond downstream kernels.

Cleaner AOSP kernels can be found, with their own limitations, on the OpenKirin page.
