ARMv8R/M architecture defines new memory protection scheme - PMSAv8 which is not compatible with PMSAv7. Key differences to PMSAv7 are: - Region geometry is defined by base and limit addresses - Addresses need to be either 32 or 64 byte aligned - No region priority due to overlapping regions are not allowed - It is unified, i.e. no distinction between data/instruction regions - Memory attributes are controlled via MAIR This patch implements support for PMSAv8 MPU defined by ARMv8R/M architecture.

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.
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.
