+          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 preffered method due to speed but it
+             limits the system to just 64MB of PCI memory. This can be 
+             problamatic if using video cards and other memory-heavy devices.
+          
+          2) If > 64MB of memory space is required, the IXP4xx can be 
+	     configured to use indirect registers to access PCI This allows 
+	     for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. 
+	     The disadvantadge of this is that every PCI access requires 
+	     three local register accesses plus a spinlock, but in some 
+	     cases the performance hit is acceptable. In addition, you cannot 
+	     mmap() PCI devices in this case due to the indirect nature
+	     of the PCI window.
+
+	  By default, the direct method is used. Choose this option if you
+	  need to use the indirect method instead. If you don't know
+	  what you need, leave this option unselected.

+ *
+ * 2) If > 64MB of memory space is required, the IXP4xx can be configured

+ *    transactions). This allows for up to 128MB (0x48000000 to 0x4fffffff)
