The Only use of PCI device enumeration here is to get the PMC base address which is a fixed value i.e. 0xFE000000. On some platforms this can be read through a non standard PCI BAR. But after Kabylake, PMC is not exposed as a PCI device anymore. There are other non standard methods like ACPI LPIT which can also be used for obtaining this value. For simplicity, this value can be hardcoded as it won't change. Since we don't have a PMC PCI device on any platform after Kabylake, this creates a foundation for future SoC support.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
