I'm trying to figure out if anyone has ported a PPC system to QEMU that is capable of booting U-Boot. Similar to the ARM versatilepb target, but for PPC instead. I've tried the Bamboo and MPC8544DS but it seems they only use stubs to OS calls and parses a DTB for info.
Did you check which configurations the Yocto project are using? They provide qemu based emulations for ARM, MIPS, PPC and x86, and I would be really surprised if the ARM and PPC configs were not based on U-Boot ... [ARM: beagleboard; PPC: mpc8315e-rdb; MIPS: routerstationpro]
I'm not familiar with what Yocto does, but at least for Freescale PPC chips QEMU does not emulate enough of the hardware to run U-Boot (at least, not without significant U-Boot hacking that I'm not aware of anyone having done). QEMU loads Linux directly.
I don't see mpc83xx support in QEMU at all.
