Macronix SPI-NANDs encode the ECC status into two bits. There are three standard situations (no bitflip, bitflips, error), and an additional possible situation which is only triggered when configuring the 0x10 configuration register, allowing to know, if there have been bitflips, whether the maximum amount of bitflips was above a configurable threshold or not. In all cases, for now, s this configuration register is unset, it means the same as "there are bitflips". This value is maybe standard, maybe not. For now, let's define it in the Macronix driver, we can safely move it to a shared place later if that is relevant.

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 reStructuredText 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.
