How much memory do these platforms have? Having just spent a bunch of
time issues about where to load what on TI platforms, I'm a little
worried about some of the locations:

Below 32MB which isn't optimal.

This doesn't leave a whole lot of space for the kernel before
overwriting either of these.

Add CONFIG_CMD_FS_GENERIC and just 'load' here and elsewhere (incl
fatload).
