MTD on intel 28F320B3 flash memory

The CFI code will not work with this chip without modification.

The 28F320B3 is a BOOT BLOCK flash part.  It contains Eight 8K regions and
63 64K regions.  The CFI code assumes that all regions are of the same size.
I am currently using this part in a design.  To get around this problem, I
changed the CFI code to treat the 8K regions as a single 64K region.
