Uups. Then it seems that I start things the wrong way. I 
start QEMU with -S -s, then I attach GDB, and GDB 
"complains" that PC is at 0x0 (and not 0x10000). How do I 
have to invoke things in the correct way (and that this 
bootloader is used)  so that system is at 0x10000 if I 
attach GDB and can start with si debugging from there?

Yes, seems that I was unclear here. Sorry. It's for an other 
board. Take this question as the first step for a new 
machine description using integrator as an example.

Thanks for your help and patience!
