-/*
- * 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
- *    problematic if using video cards and other memory-heavy targets.
- *
- * 2) If > 64MB of memory space is required, the IXP4xx can use indirect
- *    registers to access the whole 4 GB of PCI memory space (as we do below
- *    for I/O transactions). This allows currently for up to 1 GB (0x10000000
- *    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.

- * In the case of using indirect PCI, we simply return the actual PCI
- * address and our read/write implementation use that to drive the 
- * access registers. If something outside of PCI is ioremap'd, we
- * fallback to the default.
