as well.
Please review. Thanks
Implementing the Loongarch architecture defined in https://uefi.org/specs/UEFI/2.10/02_Overview.html#loongarch-platforms would make sense to me.
Supporting an architecture that does not have published UEFI standards is less convincing.
Is any of the mentioned boards being produced anymore?
Hi Heinrich,
Yes, MIPS/Loongson boards are still producing for many existing applications. There will be some future MIPS product from CIP United [1], and I think get EBBR like booting stuff implemented can save a lot of hassle.
I also intended to use UEFI as loongson3-virt firmware, supporting actual Loongson hardware is out of my scope.
I'm a hobbyist (and contractor) on MIPS stuff, so I don't really know details on LoongArch UEFI.
Thanks
