We do not have FAT suppot on flash devices yet.

I think the best way to implement this would require a two staged
approach: in the first stage, U-Boot should adapte the device driver
model we've been waiting for so long; in the second stage, the file
system support would more or less fall into place on to of the then
existing storage device drivers.

Best regards,
