James Hogan 7e5e371ee5 MIPS: Fix CPS SMP NS16550 UART defaults
The MIPS_CPS_NS16550_BASE and MIPS_CPS_NS16550_SHIFT options have no
defaults for non-Malta platforms which select SYS_SUPPORTS_MIPS_CPS
(i.e. the pistachio and generic platforms). This is problematic for
automated allyesconfig and allmodconfig builds based on these platforms,
since make silentoldconfig tries to ask the user for values, and
especially since v4.15 where the default platform was switched to
generic.

Default these options to 0 and arrange for MIPS_CPS_NS16550 to be no
when using that default base address, so that the option only has an
effect when the default is provided (i.e. Malta) or when a value is
provided by the user.

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.
