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
