Linux kernel source tree

Freescale PCIe controllers on their PCIe Root Ports do not have any
mappable PCI BAR allocate from PCIe MEM.
Information about 1MB window on BAR0 of PCIe Root Port was misleading
because Freescale PCIe controllers have at BAR0 position different register
PEXCSRBAR, and kernel correctly skipts BAR0 for these Freescale PCIe Root
Ports.
So update comment about P2020 PCIe Root Port and decrease PCIe MEM size
required for PCIe controller (pci2 node) on which is on-board xHCI
controller.
lspci confirms that on P2020 PCIe Root Port is no PCI BAR and /proc/iomem
sees that only c0000000-c000ffff and c0010000-c0011fff ranges are used.

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.
