The MTD device is blocked from writing to the SPI-NOR chip if any region of it is write-protected, even if "writeable=1" module parameter is set. Add ability to bypass this behaviour by introducing new module parameter "ignore_protestion_status" which allows to rely on the write protection mechanism of SPI-NOR chip itself, which most modern chips (since the 1990'+) have already implemented. Any erase/write operations performed on the write-protected section will be rejected by the chip.

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 reStructuredText 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.
