config IXP4XX_PCI_LEGACY
	bool "IXP4xx legacy PCI driver support"
	depends on PCI
	help
	  Selects legacy PCI driver.

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.
