extload/fatload were broken between the following two commits:

3f83c87 fs: fix number base behaviour change in fatload/ext*load
...
045fa1e fs: add filesystem switch libary, implement ls and fsload commands

(i.e. for about 50 commits)

The generic load command has been "broken" (by design...) since it was
introduced. I suppose you can change the behaviour if you want; anyone
writing "0x..." for their values presumably won't be affected, and if
people really do assume all values in U-Boot are in hex, presumably
nobody currently relies upon using non-prefixed values with the generic
load command, since it doesn't work like that right now.
