Arseniy Krasnov 4e976b1521 dt-bindings: mtd: amlogic,meson-nand: support fields for boot ROM code
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.
