[U-Boot] Using qemu-system-ppc to boot U-Boot

Hi,

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.

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.

The purpose is to emulate a network of connected machines without having to buy lots of hardware.

Best regards, Frank
