In non-EDO, tREA should be less than tRP to guarantee that the controller does not sample the IO lines too early. Unfortunately, the sunxi NAND controller does not allow us to have different values for tRP and tREH (tRP = tREH = tRW / 2). We have 2 options to overcome this limitation: 1/ Extend tRC to fulfil the tREA <= tRC / 2 constraint 2/ Use EDO mode (only works if timings->tRLOH > 0) Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
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.
