Depending on the physical memory layout, some PCI MEM areas are not usable. According to the SH7786 datasheet, the PCI MEM area from 1000_0000 to 13FF_FFFF is only usable if the physical memory layout (in MMSELR) is 1, 2, 5 or 6. In all other configurations, this PCI MEM area is not usable (because it overlaps with DRAM). Therefore, this commit adjusts the PCI SH7786 initialization to mark the relevant PCI resource as IORESOURCE_DISABLED if we can't use it.

README
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.
