During detection the logic on the NAND bus is:
/* Regular ONFI detection */
1/ read the three NAND parameter pages
/* Extended parameter page detection */
2/ send "read the NAND parameter page" commands without reading
actual data
3/ move the column pointer to the extended page and read it
If fact, as long as there is nothing happening on the NAND bus between
1/ and 3/, the operation 2/ is redundant so remove it.

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.
