You can test booting the BMC with both '-device loader' and '-drive
file'. This is necessary because of how the fb-openbmc boot sequence
works (jump to 0x20000000 after U-Boot SPL).

     wget 
https://github.com/facebook/openbmc/releases/download/openbmc-e2294ff5d31d/fby35.mtd
     qemu-system-arm -machine fby35 -nographic \
         -device loader,file=fby35.mtd,addr=0,cpu-num=0 -drive 
file=fby35.mtd,format=raw,if=mtd
