Sorry, No picture for me, I just start to consider this few days ago. > Don't get me wrong, coreboot is great > for x86 but for loongson its init framework is somewhat overkill and > initing naively is more appropriate.

I myself don't have a 2E system so as-firmware port was never done. > -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
