When you load barebox with itself you end up overwriting the running barebox with the just loaded image if using TEXT_BASE here. barebox can be started from any address in SDRAM. Isn't there a mechanism to support this with the uImage format? The U-Boot guys have the same problem with ARM_PATCH_PHYS_VIRT in the kernel aswell, so I assume this is already solved in some way, no?
