154	bool "Use indirect PCI memory access"
155	depends on PCI
156	help
157          IXP4xx provides two methods of accessing PCI memory space:
158
159          1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
160             To access PCI via this space, we simply ioremap() the BAR
161             into the kernel and we can use the standard read[bwl]/write[bwl]
162             macros. This is the preferred method due to speed but it
163             limits the system to just 64MB of PCI memory. This can be
164             problematic if using video cards and other memory-heavy devices.
165
166          2) If > 64MB of memory space is required, the IXP4xx can be
167	     configured to use indirect registers to access PCI This allows
168	     for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
169	     The disadvantage of this is that every PCI access requires
170	     three local register accesses plus a spinlock, but in some
171	     cases the performance hit is acceptable. In addition, you cannot
172	     mmap() PCI devices in this case due to the indirect nature
173	     of the PCI window.
174
175	  By default, the direct method is used. Choose this option if you
176	  need to use the indirect method instead. If you don't know
177	  what you need, leave this option unselected.
