Thank you very much Peter. What i really need is to compile a kernel by
my self, armv7 and boot it in qemu linaro. Don't bother the arguments
for now. That was just an example for armv5 modified a little to clearly
state my problem. I just need a kernel source and defconfig that can be
emulated successfully in Linaro Qemu.
