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.
The currently advertised free OOB area starts at offset 6, like
if 4 PA bytes were located right after the BBM. This is wrong as the
PA bytes are located right before the ECC bytes.
Fix the layout by allowing access to all bytes between the BBM and the
PA bytes instead of reserving 4 bytes right after the BBM.
This change breaks existing jffs2 users.

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.
