Hello,
I tried to compile openfirmware for qemu like described here http://www.openfirmware.info/Building_OFW_for_QEMU. But after running make in cpu/x86/pc/emu/build on 64bit host I get linkage error: ld -T inflate.ld inflate.lo -o inflate.o ld: i386 architecture of input file `inflate.lo' is incompatible with i386:x86-64 output

Produced rom image runs fine on qemu, but fails on qemu-kvm with error: BUG: kvm_dirty_pages_log_change: invalid parameters 0000000010000000-0000000010ffffff
Looking into it it seams like openfirmware configure cirrus framebuffer to be at address 0x10000000, but later it configures nic memory BAR with the same address (during device enumeration perhaps). Later it deconfigures nic again. Qemu somehow handles this fine, but qemu-kvm doesn't. This shouldn't work on real HW too FWIW.

Can't say much about OFW but since no one has replied yet: maybe try specifying OUTPUT_FORMAT(elf_i386) in inflate.ld or check where LD gets defined? Not sure if this code is supposed to build for both architectures or just 32-bit x86.

Only 32 bit I think. Specifying OUTPUT_FORMAT it not enough though. I had to add two lines: OUTPUT_ARCH(i386) OUTPUT_FORMAT(elf32-i386)

I checked in the changes suggested below; I hope it helps.
