Thanks Albert. Yes, this seems possible for AXP and A38x. I currently 
don't have access to the SD-card booting A38x platform though. So I 
would like to get this patch accepted now. And will send a patch for 
runtime boot-device detection later. Or perhaps somebody else will jump 
in... :)

Thanks,
Stefan
