           IXP4xx provides two methods of accessing PCI memory space:
 
-          1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).

              To access PCI via this space, we simply ioremap() the BAR
              into the kernel and we can use the standard read[bwl]/write[bwl]
              macros. This is the preferred method due to speed but it

           By default, the direct method is used. Choose this option if you
           need to use the indirect method instead. If you don't know
