do we have plan to add loongson CPU or MIPS ARCH support?
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.
OK. So, firstly, I will try to add loongson 2E support.
Great! As you may be aware, we have recently added ARMv7 support which you might want to use as an example. The architecture code is in src/arch/armv7, the CPU code is in src/cpu/samsung/{exynos5250,exynos5-common}, and the first ARM motherboard target is in src/mainboard/google/snow.
The ARM stuff is still under active development, and we are still making changes to code that was imported from another codebase (u-boot). But overall it works and we are able to load a payload and boot Linux.
