129 IXP4xx provides two methods of accessing PCI memory space:
130
131 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
132 To access PCI via this space, we simply ioremap() the BAR
133 into the kernel and we can use the standard read[bwl]/write[bwl]
134 macros. This is the preferred method due to speed but it
135 limits the system to just 64MB of PCI memory. This can be
Matt LaPlante3cb2fcc2006-11-30 05:22:59 +0100136 problematic if using video cards and other memory-heavy devices.
Linus Torvalds1da177e2005-04-16 15:20:36 -0700137
138 2) If > 64MB of memory space is required, the IXP4xx can be
139 configured to use indirect registers to access PCI This allows
140 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
Egry Gaborc41045a2006-06-04 21:22:11 +0100141 The disadvantage of this is that every PCI access requires
Linus Torvalds1da177e2005-04-16 15:20:36 -0700142 three local register accesses plus a spinlock, but in some
143 cases the performance hit is acceptable. In addition, you cannot
144 mmap() PCI devices in this case due to the indirect nature
145 of the PCI window.
146
147 By default, the direct method is used. Choose this option if you
148 need to use the indirect method instead. If you don't know
149 what you need, leave this option unselected.
