[U-Boot] USB and FAT

[Dennis Kerrisk]

	Unfortunately the Ubicom board is not supported in the mainline.
So I would have to report it. Does this work on a board that supports
Mainline code? I would like to eliminate that as the problem. My guess 
Is that there is a bug in the Ubicom port, probably dealing with 
The USB. I seem to be able load small files 40k with no problem.
I really would like to know if anyone has loaded large files 
With mainline code so I can eliminate u-boot code .

Of course it is possible that U-Boot crashes, for example when there
are hardware problems, or when there are bugs in the port to your
board, or eventually even if you are running into a bug in common
code.

If your board is supported in mainline, then running the latest
version is strongly recommended.
