I think Thomas raises a good point. The important thing is that 'make fooboard' produces everything to boot the board (when possible). But at the end of the day, it comes down to the user needs to understand how to boot their board. The TI MLO file can be dd'ed to an SD card and booted too, for example. -- Tom _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
