You would still need to symlink /usr/lib/u-boot/qemu-ppce500/uboot.elf to the location that qemu expects it. > I dunno what's the name to suggest for this package, since > u-boot-qemu is already taken and it provides different images, > not directly used by qemu. Maybe qemu-uboot or something, dunno. I would just add it to u-boot-qemu; it is still a small number of targets and each one is not very large, and while qemu does not use the other targets shipped in u-boot-qemu out-of-the-box, they can be used with qemu. > There's a bug open in the Debian BTS about this, #756833 , - open > for a long time already.
