1config PCI
2 bool "PCI support"
3 depends on SYS_SUPPORTS_PCI
4 help
5 Find out whether you have a PCI motherboard. PCI is the name of a
6 bus system, i.e. the way the CPU talks to the other stuff inside
7 your box. If you have PCI, say Y, otherwise N.

9config SH_PCIDMA_NONCOHERENT
10 bool "Cache and PCI noncoherent"
11 depends on PCI
12 default y
13 help
14 Enable this option if your platform does not have a CPU cache which
15 remains coherent with PCI DMA. It is safest to say 'Y', although you
16 will see better performance if you can say 'N', because the PCI DMA
17 code will not have to flush the CPU's caches. If you have a PCI host
18 bridge integrated with your SH CPU, refer carefully to the chip specs
19 to see if you can say 'N' here. Otherwise, leave it as 'Y'.
