Boot ROM code on Meson requires that some pages on NAND must be written in special mode: "short" ECC mode where each block is 384 bytes and scrambling mode is on. Such pages are located on the chip in the following way (for example): [ p0 ][ p1 ][ p2 ][ p3 ][ p4 ][ p5 ][ p6 ][ p7 ] ... [ pN ] ^ ^ ^ ^ pX is page number "X". "^" means "special" page used by boot ROM - e.g. every 2nd page in the range of [0, 7]. Step (2 in example is set by 'amlogic,boot-page-step' field. Last page in range (7 in example) is set by 'amlogic,boot-pages' field.

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 reStructuredText 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.
