$ cd u-boot.git
$ make distclean
$ make qemu_mips_config
$ make CROSS_COMPILE=mips-linux-
$ cp -a u-boot.bin mips_bios.bin
$ qemu-system-mips -L . /dev/nulll
at this point, qemu console window appears but I can't see any u-boot's

I use u-boot-1.3.1 + qemu patch, gcc 4.2.1 and binutils 18.104.22.168.1.
Am I miss something?
