The RISC-V ISA manual says that PMPs are WARL, but it appears the K210 doesn't implement them and instead traps on the unsupported accesses. This patch handles those traps by just skipping the PMP initialization entirely, under the theory that machines that trap on PMP accesses must allow memory accesses as otherwise they're pretty useless.

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.
