This patch adds, - support more CPU variants other than MIPS 4K - without changing the code. In other words, every U-Boot/MIPS user other than MIPS 4K must change cpu/mips/config.mk as he wants. I thought this patch is more beneficial for MIPS users even if breaking old gcc 2.96 support. That's all. I don't want to argue with you about this issue. If you disagree, I'll drop this from my queue. I don't mind, I can live without this change. Shinya
