This does not apply on current spi-nor/next. We've changed how the
flash_info flags are handled. We also require to dump the SPI NOR
sysfs entries under the comment section ---. I'll update the
documentation to add some guidelines on how new flash additions or
flash updates should be proposed. Sometime this week, or maybe
next.
