JESD216D.01 says that when the address width can be 3 or 4, it defaults to 3 and enters 4-byte mode when given the appropriate command. So, when we see a configurable width, default to 3 and let flash that default to 4 change it in a post-bfpt fixup. This fixes SMPT parsing for flashes with configurable address width. If the SMPT descriptor advertises variable address width, we use nor->addr_width as the address width. But since it was not set to any value from the SFDP table, the read command uses an address width of 0, resulting in an incorrect read being issued.

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.
