Johan Jonker 70643e98cb mtd: rawnand: rockchip: Align hwecc vs. raw page helper layouts 
[ Upstream commit ea690ad78d ]

Currently, read/write_page_hwecc() and read/write_page_raw() are not
aligned: there is a mismatch in the OOB bytes which are not
read/written at the same offset in both cases (raw vs. hwecc).

This is a real problem when relying on the presence of the Page
Addresses (PA) when using the NAND chip as a boot device, as the
BootROM expects additional data in the OOB area at specific locations.

Rockchip boot blocks are written per 4 x 512 byte sectors per page.
Each page with boot blocks must have a page address (PA) pointer in OOB
to the next page. Pages are written in a pattern depending on the NAND chip ID.

Generate boot block page address and pattern for hwecc in user space
and copy PA data to/from the already reserved last 4 bytes before ECC
in the chip->oob_poi data layout.

Align the different helpers. This change breaks existing jffs2 users.

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.

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.
