I hesitate to add this patch, as I'm not convinced that this is a problem that should be addressed in U-Boot. U-Boot seems to work fine on the MIPS systems I can test myself, and Masami Komiya also reported success.
Please explain why you think this is an U-Boot issue, and not instead a problem with the MV kernel?
Best regards,
Wolfgang Denk

Ok, I will solve it in kernel instead. Please drop patch.
