Max Krummenacher 10c586da9f Revert "Revert "mtd: rawnand: gpmi: Fix setting busy timeout setting""
This reverts commit 15a3adfe75.

The backport of [1] relies on having [2] also backported. Having only
one of the two results in a bogus hw->timing1 setting.

If only [2] is backportet the 16 bit register value likely underflows
resulting in a busy_wait_timeout of 0.
Or if only [1] is applied the value likely overflows with chances of
having last 16 LSBs all 0 which would then result in a
busy_wait_timeout of 0 too.

Both cases may lead to NAND data corruption, e.g. on a Colibri iMX7
setup this has been seen.

[1] commit 0fddf9ad06fd ("mtd: rawnand: gpmi: Set WAIT_FOR_READY timeout based on program/erase times")
[2] commit 06781a5026350 ("mtd: rawnand: gpmi: Fix setting busy timeout setting")

README

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.
