There are bit fields which persist in the MIPS CONFIG and CONFIG6 registers, but haven't been described in the generic mipsregs.h header so far. In particular, the generic CONFIG bitfields are BE - endian mode, BM - burst mode, SB - SimpleBE, OCP interface mode indicator, UDI - user-defined "CorExtend" instructions, DSP - data scratch pad RAM present, ISP - instruction scratch pad RAM present, etc. The core-specific CONFIG6 bitfields are JRCD - jump register cache prediction disable, R6 - MIPSr6 extensions enable, IFUPerfCtl - IFU performance control, SPCD - sleep state performance counter, DLSB - disable load/store bonding. A new exception code reported in the ExcCode field of the Cause register: 30 - Parity/ECC error exception happened on either fetch, load or cache refill. Lets add them to the mipsregs.h header to be used in future platform code, which have them utilized.

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.
