Dear Frank,

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]
If there's no target supported yet, what about a QEMU target the support booting an ARM target in big-endian mode? Big-endian is important in order to test some endian dependent code.
If you need BE systems, use PPC. For ARM, they are just a tiny minority (so far at least) that I don't think it makes sense to invest efforts in these.
Best regards,
Wolfgang Denk
