According to the MIPS32 InterAptiv software manual error codes 24 - 26 of CM2 indicate L2 ECC/parity error with switching to a corresponding errors info fields. This patch provides these errors parsing code, which handles the read/write uncorrectable and correctable ECC/parity errors, and prints instruction causing the fault, RAM array type, cache way/dword and syndrome associated with the faulty data.

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.
