That was my question to Edgar, which was not answered. In u-boot, one would change some environment variables. With this code in qemu, the only recourse would be to edit ppc440_bamboo.c and rebuild. Perhaps in the future we can do something more sophisticated by specifying load addresses in a qemu device tree, but I don't understand that stuff enough to know if that is an intended use. -Hollis
