do we have plan to add loongson CPU or MIPS ARCH support?
Loongson platforms are very different from any x86 boards. I believe that coreboot in this case would get more in the way than help. I ported GRUB to be firmware on Yeloong 2F and Fuloong 2F. Everything coreboot does on x86 including video init holds under 1000 lines of assembly code for yeeloong. See fwstart.S in GRUB tree. What is your goal? Can we perhaps adapt GRUB to your needs?
There is no plan that I know of.
It seems no person from loongson contribute to this, and can I try to make some efforts on this topic?
I guess people contributing stuff are always welcome. Though I have no experience with loongson and MIPS, so I cannot comment how feasible this is.
Thanks,
Paul
