It doesn't matter what the ATA standard permits in this case.  We need 
to assure that the OCTEON Boot Bus standard is respected.  There are 
several timing parameters that we have to set based on the documented 
properties of the device.  Ideally if we try to run bus cycles for 
non-ATA/CF devices that share the signal lines of the Boot Bus, they 
should  not interfere with the CF interface.
