Move PCI configuration space, MMIO and memory to the KIO range to free vmalloc area and use static TLB to access them. Move MMIO to the beginning of KIO and define PCI_IOBASE as XCHAL_KIO_BYPASS_VADDR to match it. Reduce number of supported PCI buses to 0x3f so that ECAM window fits into first 64MB of the KIO. Reduce size of the PCI memory window to 128MB so that it fits into KIO. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
