132 IXP4xx provides two methods of accessing PCI memory space:
133
134 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
135 To access PCI via this space, we simply ioremap() the BAR
136 into the kernel and we can use the standard read[bwl]/write[bwl]
137 macros. This is the preferred method due to speed but it
138 limits the system to just 64MB of PCI memory. This can be
139 problamatic if using video cards and other memory-heavy devices.
140
141 2) If > 64MB of memory space is required, the IXP4xx can be
142 configured to use indirect registers to access PCI This allows
143 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
Egry Gaborc41045a2006-06-04 21:22:11 +0100144 The disadvantage of this is that every PCI access requires
Linus Torvalds1da177e2005-04-16 15:20:36 -0700145 three local register accesses plus a spinlock, but in some
146 cases the performance hit is acceptable. In addition, you cannot
147 mmap() PCI devices in this case due to the indirect nature
148 of the PCI window.
149
150 By default, the direct method is used. Choose this option if you
151 need to use the indirect method instead. If you don't know
152 what you need, leave this option unselected.
