The Kioxia/Toshiba TH58NVG2S3HBAI4 NAND memory is not ONFI compliant. The timings of the NAND chip memory are quite close to ONFI mode 4 but is breaking that spec. By providing our own set of timings, erase block read speed is increased from 6910 kiB/s to 13490 kiB/s and erase block write speed is increased from 3350 kiB/s to 4410 kiB/s. Tested on IMX6SX which has a NAND controller supporting EDO mode.

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.
