146	depends on PCI
147	help
148          IXP4xx provides two methods of accessing PCI memory space:
149
150          1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
151             To access PCI via this space, we simply ioremap() the BAR
152             into the kernel and we can use the standard read[bwl]/write[bwl]
153             macros. This is the preferred method due to speed but it
154             limits the system to just 64MB of PCI memory. This can be
155             problematic if using video cards and other memory-heavy devices.
156
157          2) If > 64MB of memory space is required, the IXP4xx can be
158	     configured to use indirect registers to access PCI This allows
159	     for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
160	     The disadvantage of this is that every PCI access requires
161	     three local register accesses plus a spinlock, but in some
162	     cases the performance hit is acceptable. In addition, you cannot
163	     mmap() PCI devices in this case due to the indirect nature
164	     of the PCI window.
165
166	  By default, the direct method is used. Choose this option if you
167	  need to use the indirect method instead. If you don't know
168	  what you need, leave this option unselected.
