Some SPI-NAND chips do not support on-die ECC. For these chips, correction must apply on the SPI controller end. In order to avoid doing all the calculations by software, Macronix provides a specific engine that can offload the intensive work. Add Macronix ECC engine support, this engine can work in conjunction with a SPI controller and a raw NAND controller, it can be pipelined or external and supports linear and syndrome layouts. Right now the simplest configuration is supported: SPI controller external and linear ECC engine.

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.
