Miquel Raynal d71dac3b89 Topic branch bringing-in changes related to the support of ECC engines 
that can be used by SPI controllers to manage SPI NANDs as well as
 possibly by parallel NAND controllers. In particular, it brings support
 for Macronix ECC engine that can be used with Macronix SPI controller.
 
 The changes touch the NAND core, the NAND ECC core, the spi-mem layer, a
 SPI controller driver and add a new NAND ECC driver, as well as a number
 of binding updates.
 
 Binding changes:
 * Vendor prefixes: Clarify Macronix prefix
 * SPI NAND: Convert spi-nand description file to yaml
 * Raw NAND chip: Create a NAND chip description
 * Raw NAND controller:
   - Harmonize the property types
   - Fix a comment in the examples
   - Fix the reg property description
 * Describe Macronix NAND ECC engine
 * Macronix SPI controller:
   - Document the nand-ecc-engine property
   - Convert to yaml
   - The interrupt property is not mandatory
 
 NAND core changes:
 * ECC:
   - Add infrastructure to support hardware engines
   - Add a new helper to retrieve the ECC context
   - Provide a helper to retrieve a pilelined engine device
 
 NAND-ECC changes:
 * Macronix ECC engine:
   - Add Macronix external ECC engine support
   - Support SPI pipelined mode
 
 SPI-NAND core changes:
 * Delay a little bit the dirmap creation
 * Create direct mapping descriptors for ECC operations
 
 SPI-NAND driver changes:
 * macronix: Use random program load
 
 SPI changes:
 * Macronix SPI controller:
   - Fix the transmit path
   - Create a helper to configure the controller before an operation
   - Create a helper to ease the start of an operation
   - Add support for direct mapping
   - Add support for pipelined ECC operations
 * spi-mem:
   - Introduce a capability structure
   - Check the controller extra capabilities
   - cadence-quadspi/mxic: Provide capability structures
   - Kill the spi_mem_dtr_supports_op() helper
   - Add an ecc parameter to the spi_mem_op structure

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.
