Because that what's the hardware does - actually,  from memory I thought
this family only claimed 16M.

The reason for the larger size is given in the datasheet - it's multiple
mapped copies of the RAM so as top have automatic byteswapping.  So something
to beware of if this device is used under the PPC emulation.
