144 config IXP4XX_INDIRECT_PCI
145 bool "Use indirect PCI memory access"
148 IXP4xx provides two methods of accessing PCI memory space:
150 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
151 To access PCI via this space, we simply ioremap() the BAR
152 into the kernel and we can use the standard read[bwl]/write[bwl]
153 macros. This is the preferred method due to speed but it
154 limits the system to just 64MB of PCI memory. This can be
155 problematic if using video cards and other memory-heavy devices.
157 2) If > 64MB of memory space is required, the IXP4xx can be
158 configured to use indirect registers to access PCI This allows
159 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
160 The disadvantage of this is that every PCI access requires
161 three local register accesses plus a spinlock, but in some
162 cases the performance hit is acceptable. In addition, you cannot
163 mmap() PCI devices in this case due to the indirect nature
166 By default, the direct method is used. Choose this option if you
167 need to use the indirect method instead. If you don't know
168 what you need, leave this option unselected.
