 I see the file in the source tree, but that does not address my concern.  
The Malta board does not include any x86 firmware and so requiring one is 
IMHO the wrong way to go.  The setup should specify the onboard NIC has no 
ROM and should not require an image for it.  Having to distribute x86 
firmware with a MIPS simulator and toolchain makes no sense to me (OK, we 
could probably `dd' /dev/zero to substitute a dummy image, but that is 
more like a hack to me than a proper solution).
