Guang, from all of the respondents I probably are the most inexperienced
one, so my answers might be incorrect. One of the strong points of
coreboot is its PCI initialization framework, the ability to configure
it with Kconfig and the ability to customize it because of the payload
concept, where coreboot only initializes only the minimum of the
hardware and a payload, like SeaBIOS, FILO and GRUB, can take over.

As I do not know the Loongson/MIPS architecture, I have no idea if the
coreboot “framework” is suitable or not for it. From coreboot’s
perspective it would be nice if you could spend the time trying to do a
Loongson/MIPS port. I also cannot remember if that has been tried in the
