* MTD

Apart from preventing the mtdblk to run on top of ftl or ubiblk (which
may cause security issues and has no meaning anyway), there are a few
misc fixes.

* Raw NAND

Two meaningful changes this time. The conversion of the brcmnand driver
to the ->exec_op() API, this series brought additional changes to the
core in order to help controller drivers to handle themselves the WP pin
during destructive operations when relevant.

There is also a series bringing important fixes to the sequential read
feature.

As always, there is as well a whole bunch of miscellaneous W=1 fixes,
together with a few runtime fixes (double free, timeout value, OOB
layout, missing register initialization) and the usual load of remove
callbacks turned into void (which led to switch the txx9ndfmc driver to
use module_platform_driver()).

* SPI NOR

SPI NOR comes with die erase support for multi die flashes, with new
octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated
documentation about what the contributors shall consider when proposing
flash additions or updates.

Michael Walle stepped out from the reviewer role to maintainer.
