* 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
* targets.
*
* 2) If > 64MB of memory space is required, the IXP4xx can be configured
* to use indirect registers to access PCI (as we do below for I/O
* transactions). This allows for up to 128MB (0x48000000 to 0x4fffffff)
* of memory on the bus. The disadvantage 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.
