Add support for the layout used by 2kiB page NAND chips requesting at least 8-bit of correction per 512 bytes. This layout requires a bit of handling as: 1/ It can only fit if the NAND chip has at least 128 OOB bytes. 2/ The Bad Block Markers are located in the middle of the data bytes and shall not be used. 3/ It has been experimentally observed that, for certain layouts, the ECC engine tries to correct data while it should not because the errors are uncorrectable. While this is harmless for truly bad pages, it creates bitflips in empty pages. To avoid such scenario that augments artificially the number of bitflips we re-read in raw mode the entire page instead of just the ECC bytes. This is done only for this layout to avoid an unneeded penalty with other setups. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: Boris Brezillon <boris.brezillon@bootlin.com> |

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
