213config IXP4XX_INDIRECT_PCI
214	bool "Use indirect PCI memory access"
215	depends on PCI
216	help
217          IXP4xx provides two methods of accessing PCI memory space:
218
219          1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
220             To access PCI via this space, we simply ioremap() the BAR
221             into the kernel and we can use the standard read[bwl]/write[bwl]
222             macros. This is the preferred method due to speed but it
223             limits the system to just 64MB of PCI memory. This can be
224             problematic if using video cards and other memory-heavy devices.
225
226	  2) If > 64MB of memory space is required, the IXP4xx can be
227	     configured to use indirect registers to access the whole PCI
228	     memory space. This currently allows for up to 1 GB (0x10000000
229	     to 0x4FFFFFFF) of memory on the bus. The disadvantage of this
230	     is that every PCI access requires three local register accesses
231	     plus a spinlock, but in some cases the performance hit is
232	     acceptable. In addition, you cannot mmap() PCI devices in this
233	     case due to the indirect nature of the PCI window.
234
235	  By default, the direct method is used. Choose this option if you
236	  need to use the indirect method instead. If you don't know
237	  what you need, leave this option unselected.
