212 config IXP4XX_INDIRECT_PCI
213 bool "Use indirect PCI memory access"
216 IXP4xx provides two methods of accessing PCI memory space:
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.
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.
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.
