Note PCIE_IPROC depends on ARCH_BCM_IPROC. By defaulting it to y, it will be automatically enabled for all iProc family of SoCs. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The convention for device drivers is to make them all optional. What you can do however is to add depends on ARCH_BCM_IPROC || COMPILE_TEST to the driver to do the reverse and not let the driver be turned on unless IPROC is selected or you are just testing the build. A lot of distros just turn on all drivers, so this way you wouldn't accidentally enable it for a kernel that doesn't support IPROC.
