 | 
 | This is a red herring.  The conflict checking for `msize' (aha `iosiz')
 | in userconfig.c is complete nonsense (identical, nonzero sizes cause a
 | bogus conflict).  You can eliminate this source of confusion by reducing
 | one of the sizes a little.  This is harmless because the size is not
 | actually used by the cy driver.  It is just printed by the boot code.
 
 I figured it was. I mention it for completeness.
 
 | 
 | The conflict checking for the [maddr, maddr + msize) range is also
 | broken.  Only one endpoint of the new range is checked.  This doesn't
 | matter here.  It just fails to detect some conflicts.

 Indeed.

 | Perhaps its address is wrong (not much else case go wrong in the probe).
 
 I have checked and double checked the dipswitches.

 You mean pull it out? Or just pull it out of the config?
