config IXP4XX_INDIRECT_PCI
bool "Use indirect PCI memory access"
depends on IXP4XX_PCI_LEGACY
help
IXP4xx provides two methods of accessing PCI memory space:
1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
To access PCI via this space, we simply ioremap() the BAR
into the kernel and we can use the standard read[bwl]/write[bwl]
macros. This is the preferred method due to speed but it
limits the system to just 64MB of PCI memory. This can be
problematic if using video cards and other memory-heavy devices.
2) If > 64MB of memory space is required, the IXP4xx can be
configured to use indirect registers to access the whole PCI
memory space. This currently allows for up to 1 GB (0x10000000
to 0x4FFFFFFF) of memory on the bus. The disadvantage of this
is that every PCI access requires three local register accesses
plus a spinlock, but in some cases the performance hit is
acceptable. In addition, you cannot mmap() PCI devices in this
case due to the indirect nature of the PCI window.
By default, the direct method is used. Choose this option if you
need to use the indirect method instead. If you don't know
what you need, leave this option unselected.
