commit a3c4c2339f8948b0f578e938970303a7372e60c0 upstream.
Change calculating of position page containing BBM
If none of BBM flags are set then function nand_bbm_get_next_page
reports EINVAL. It causes that BBM is not read at all during scanning
factory bad blocks. The result is that the BBT table is build without
checking factory BBM at all. For Micron flash memories none of these
flags are set if page size is different than 2048 bytes.
Address this regression by:
- adding NAND_BBM_FIRSTPAGE chip flag without any condition. It solves
issue only for Micron devices.
- changing the nand_bbm_get_next_page_function. It will return 0
if no of BBM flag is set and page parameter is 0. After that modification
way of discovering factory bad blocks will work similar as in kernel
version 5.1.

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.
