 100 config IXP4XX_INDIRECT_PCI
 101         bool "Use indirect PCI memory access"
 102         help
 103           IXP4xx provides two methods of accessing PCI memory space:
 104
 105           1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
 106              To access PCI via this space, we simply ioremap() the BAR
 107              into the kernel and we can use the standard read[bwl]/write[bwl]
 108              macros. This is the preferred method due to speed but it
 109              limits the system to just 64MB of PCI memory. This can be
 110              problamatic if using video cards and other memory-heavy devices.
 111
 112           2) If > 64MB of memory space is required, the IXP4xx can be
 113              configured to use indirect registers to access PCI This allows
 114              for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
 115              The disadvantadge of this is that every PCI access requires
 116              three local register accesses plus a spinlock, but in some
 117              cases the performance hit is acceptable. In addition, you cannot
 118              mmap() PCI devices in this case due to the indirect nature
 119              of the PCI window.
 120
 121           By default, the direct method is used. Choose this option if you
 122           need to use the indirect method instead. If you don't know
 123           what you need, leave this option unselected.
