Arnd Bergmann 8fe743b5eb PCI: Add CONFIG_MMU dependency
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.

Choose this option if you have a recent AMD Radeon graphics card.
If M is selected, the module will be called amdgpu.

Choose this option if you want to enable experimental support

SI is already supported in radeon. Experimental support for SI
in amdgpu will be disabled by default and is still provided by
radeon. Use module options to override this:

Choose this option to enable ISP IP support for AMD SOCs.
This adds the ISP (Image Signal Processor) IP driver and wires
it up into the amdgpu driver. It is required for cameras
on APUs which utilize mipi cameras.
