For dual-rank LPDDR4, result data for any command is placed in byte 0 and byte 3 of the corresponding MR register by the firmware. Single-rank RAM was supposed to work the same way. However, due to a firmware bug, result values are only placed in byte 3 of the corresponding MR register. Since byte 3 works for single-rank and dual-rank setups, we change the Linux driver to always use byte 3, thus returning the correct value in either case.

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.
