Dear Hiroshi,
 
    I modified the files with your patches,
    and made my u-boot image again,
    I got the following error message:
 
    cpu/mips/start.o /home/charles/work/u-boot-1.1.4/cpu/mips/start.S
    cc1: error: invalid option `-mcpu=4kc'
 
    Does it mean the cpu selection was wrong?
    Thanks a lot.
