So DFU was / is the only official way to update GTA02 bootloader. This only means that the ports of U-Boot and Linux to that hardware were inconsistent, which means that at least one of them can be considered broken. [And I'm tempted to add that this might eventually be a consequence of the fact that all this work was done without ever getting in touch with the U-Boot community. Likewise, no code or fixes have been contributed back into mainline.] I think it's unfair to blame U-Boot for a poor on incorrect implementation of the NAND driver on this specific hardware.
