Great, thanks a lot Phil!

We've managed to run u-boot with serial output and switch to the kernel 
read from the same sd card image we use on real hardware.

It also requires the small hack to make qemu simulate the early boot 
sequence from the rpi firmware, following the explanations of Peter:

     mkimage -A arm -T kernel -C none -O linux -a 0x800 -e 0x800 -d 
u-boot.bin u-boot.img
     qemu ... -kernel u-boot.img ...

After that, we are getting kernel panics at the point where our 
initramfs' init get executed. We are not yet sure about the exact 
reason, but that's still a great improvement.
