	help
	  Find out whether you have a PCI motherboard. PCI is the name of a
	  bus system, i.e. the way the CPU talks to the other stuff inside
	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
	  VESA. If you have PCI, say Y, otherwise N.

	  The PCI-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>, contains valuable
	  information about which PCI hardware does work under Linux and which
	  doesn't.

config SH_PCIDMA_NONCOHERENT
	bool "Cache and PCI noncoherent"
	depends on PCI
	default y
	help
	  Enable this option if your platform does not have a CPU cache which
	  remains coherent with PCI DMA. It is safest to say 'Y', although you
	  will see better performance if you can say 'N', because the PCI DMA
	  code will not have to flush the CPU's caches. If you have a PCI host
	  bridge integrated with your SH CPU, refer carefully to the chip specs
	  to see if you can say 'N' here. Otherwise, leave it as 'Y'.
