Gregory CLEMENT f62a9cc0c2 MIPS: SMP-CPS: Fix address for GCR_ACCESS register for CM3 and later
[ Upstream commit a263e5f309f32301e1f3ad113293f4e68a82a646 ]

When the CM block migrated from CM2.5 to CM3.0, the address offset for
the Global CSR Access Privilege register was modified. We saw this in
the "MIPS64 I6500 Multiprocessing System Programmer's Guide," it is
stated that "the Global CSR Access Privilege register is located at
offset 0x0120" in section 5.4. It is at least the same for I6400.

This fix allows to use the VP cores in SMP mode if the reset values
were modified by the bootloader.

Based on the work of Vladimir Kondratiev
<vladimir.kondratiev@mobileye.com> and the feedback from Jiaxun Yang
<jiaxun.yang@flygoat.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.
