config PCI
bool "PCI support"
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. If you have PCI, say Y, otherwise N.
The PCI-HOWTO, available from
<>, contains valuable
information about which PCI hardware does work under Linux and which
bool "Cache and PCI noncoherent"
depends on PCI
default y
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'.
# This is also board-specific
config PCI_AUTO
depends on PCI
default y
depends on PCI_AUTO
default y if !SH_DREAMCAST
Selecting this option will cause the PCI auto code to leave your
BAR values alone. Otherwise they will be updated automatically. If
for some reason, you have a board that simply refuses to work
with its resources updated beyond what they are when the device
is powered up, set this to N. Everyone else will want this as Y.
