135	depends on PCI
136	help
137          IXP4xx provides two methods of accessing PCI memory space:
138
139          1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
140             To access PCI via this space, we simply ioremap() the BAR
141             into the kernel and we can use the standard read[bwl]/write[bwl]
142             macros. This is the preferred method due to speed but it
143             limits the system to just 64MB of PCI memory. This can be
144             problematic if using video cards and other memory-heavy devices.
145
146          2) If > 64MB of memory space is required, the IXP4xx can be
147	     configured to use indirect registers to access PCI This allows
148	     for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
149	     The disadvantage of this is that every PCI access requires
150	     three local register accesses plus a spinlock, but in some
151	     cases the performance hit is acceptable. In addition, you cannot
152	     mmap() PCI devices in this case due to the indirect nature
153	     of the PCI window.
154
155	  By default, the direct method is used. Choose this option if you
156	  need to use the indirect method instead. If you don't know
157	  what you need, leave this option unselected.
