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