-/*
- * 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.
