The comment in spinand_write_to_cache_op() says that spinand_ondie_ecc_prepare_io_req() should 0xff fill the OOB area but it doesn't. This causes the OOB area to get filled with zeros and anytime the first page in a block the bad block marker is cleared and it becomes a bad block on the next boot. This was observed on Longsys FORSEE branded parts and might be specific to these parts.

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.
