[U-Boot-Users] Question about MIPS 4KE core

Hi, all I am using U-boot 1.2.0, and intend to port it to a MIPS 4KE core cpu. From the hints in README, I read the source code in general. :) My Question is: would cpu/mips/*.s compatiable for a 4KE one? I have noticed that there is only a board for MIPS 4K, and some condition macro used in asm files. If I want to port succ, should I modify something in cpu/mips/*.s or only implement the source files in board/_MYBOARD_/ ? Thanks a lot.

PS: Sorry for last message...
