Example usage:

# ln -s u-boot.bin mips_bios.bin
start it:
qemu-system-mips -L . /dev/null -nographic

or

if you use a qemu version after commit 4224

create image:
# dd of=flash bs=1k count=4k if=/dev/zero
# dd of=flash bs=1k conv=notrunc if=u-boot.bin
start it:
# qemu-system-mips -pflash flash -monitor null -nographic
