100config IXP4XX_INDIRECT_PCI
101 bool "Use indirect PCI memory access"
102 help
103 IXP4xx provides two methods of accessing PCI memory space:
104
105 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
106 To access PCI via this space, we simply ioremap() the BAR
107 into the kernel and we can use the standard read[bwl]/write[bwl]
108 macros. This is the preferred method due to speed but it
109 limits the system to just 64MB of PCI memory. This can be
110 problamatic if using video cards and other memory-heavy devices.
111
112 2) If > 64MB of memory space is required, the IXP4xx can be
113 configured to use indirect registers to access PCI This allows
114 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
115 The disadvantadge of this is that every PCI access requires
116 three local register accesses plus a spinlock, but in some
117 cases the performance hit is acceptable. In addition, you cannot
118 mmap() PCI devices in this case due to the indirect nature
119 of the PCI window.
120
121 By default, the direct method is used. Choose this option if you
122 need to use the indirect method instead. If you don't know
123 what you need, leave this option unselected.
