[ Upstream commitfc9e18f9e9] Under the following conditions: * after rounding up by 4 the number of bytes to transfer (this is related to the controller's internal constraints), * if this (rounded) amount of data is situated beyond the end of the device, * and only in NV-DDR mode, the Arasan NAND controller timeouts. This currently can happen in a particular helper used when picking software ECC algorithms. Let's prevent this situation by refusing to use the NV-DDR interface with software engines.

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.
