It turns out that there are no platforms that have PCI but don't have an MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing kernels for those platforms a lot, and avoids a lot of inadvertent build regressions. Add a dependency for CONFIG_PCI and remove all the ones for PCI specific device drivers that are currently marked not having it. There are a few platforms that have an optional MMU, but they usually cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is mainly for historic reasons, and anyone using those chips should really use the MMU these days.

This is a KMS driver for Matrox G200 chips. It supports the original
|
|
MGA G200 desktop chips and the server variants. It requires 0.3.0
|
|
of the modesetting userspace driver, and a version of mga driver
|
|
that will fail on KMS enabled devices.

help
|
|
The VRAM of the G200 is mapped with Write-Combine to improve
|
|
performances. This can interfere with real-time tasks; even if they
|
|
are running on other CPU cores than the graphics output.
|
|
Enable this option only if you run realtime tasks on a server with a
|
|
Matrox G200.
