Ok. I'd like to make sure that

 * Which version of U-Boot do you use?

 * How do you configure CFGs below?
   - CFG_ICACHE_SIZE
   - CFG_DCACHE_SIZE
   - CFG_CACHELINE_SIZE

And if possible, please post the diff regarding `cpu/mips' like this,

   $ diff -uprN u-boot-X.Y.Z{.orig,-yours}/cpu/mips > my.patch

Thanks in advance,

  Shinya
