AFAIK the current low level code is pretty specific to one processor -
some Infineon chip used on one of the ports. It kinda works on a few
others. There are a number of problems extending that to 'all MIPS'
or even just MIPS32 compatible parts: cache init/cache handling, CP0
handling, hardcoded checks for denx toolchain, and probably a few
others that I've forgotten.
That said, I mean no disrespect to Shinya and other maintainers, I
think Shinya is doing a great job. We've discussed these issues, and
it'll just take time and effort to clean up what's there. U-boot is
the bootloader for PPC, but for MIPS many people use RedBoot or YAMON
or CFE or pmon, depending on what their eval board came with, so it's
a smaller user base.

It does, but we started from a patch for the Au1500 that made it a lot
easier. I think you also know I've submitted a fair number of bug
fixes and patches for stuff along the way.
As far as getting the job done, since he has a platform that already
suits most of his needs, it seems like adding basic ATA support and
FAT support to that in C code would be easier than trying to work
through the low-level issues with the u-boot MIPS code on a proc that
is not supported. (Particularly if he doesn't have access to good
debugging tools, or is not well versed in the low-level arch details)
