This looks like the source of the problem: http://git.qemu.org/?p=3Dqemu.git;a=3Dcommitdiff;h=3D3812c71ffaa2cf733c30= 87792b859fef30b7545f = What works: ---------- Basic invocation qemu-system-ppc -machine ppce500 -monitor stdio -bios u-boot.e500 works, I get the uboot prompt and this: (qemu) info roms addr=3D0000000000f00000 size=3D0x044b8c mem=3Dram name=3D"phdr #0: .../qe= mu/share/qemu/u-boot.e500" addr=3D0000000000f81000 size=3D0x006b00 mem=3Dram name=3D"phdr #1: .../qe= mu/share/qemu/u-boot.e500" = Passing u-boot.e500 image as kernel (-bios u-boot.e500 -kernel u-boot.e50= 0) appears to work, $qemu_kernel_addr is filled in, though (as expected) ub= oot complains about the image format.

() The thing is, this used to work +- before the commit, where I'd just pass the image as -kernel option, and it booted. = If I do that now (w/o the -bios option, using the exact same image), the = kernel gets loaded twice, only at different addresses (the cause is obvious= from the commit), causing overlap error: qemu-system-ppc -machine ppce500 -monitor stdio -kernel boot/vmlinux -m= 1024 QEMU 2.4.1 monitor - type 'help' for more information (qemu) rom: requested regions overlap (rom boot/vmlinux. free=3D0x0000000= 0027492fc, addr=3D0x0000000002000000) To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1596832/+subscriptions
