Add a driver to support the NAND flash controller of the MediaTek MT7621
System-on-Chip device. (This one is the MIPS based parts from Mediatek).
This code is a re-working of the earlier patches for this hardware that
have been floating around the internet for years:
https://github.com/ReclaimYourPrivacy/cloak/blob/master/target/linux/ramips/patches-3.18/0045-mtd-add-mt7621-nand-support.patch
This is a much cleaned up version, put in staging to start with.
It does still have some problems, mainly that it still uses a lot of the
mtd raw nand legacy support.
The driver not only compiles, but it works well on the small range of
hardware platforms that it has been used on so far. I have been using
for quite a while now, cleaning up as I get time.
So... I am looking for comments on the best approach forward with this.
At least in staging it can get some more eyeballs going over it.
There is a mediatek nand driver already, mtk_nand.c, for their ARM based
System-on-Chip devices. That hardware module looks to have some hardware
similarities with this one. At this point I don't know if that can be
used on the 7621 based devices. (I tried a quick and dirty setup and had
no success using it on the 7621).
Thoughts?

Hi Greg,
Thanks for posting this driver.
But I would like to mention that the openwrt community is currently
working on a
new version which is based a newer version of the MediaTek vendor driver.
That version is currently targeted for the openwrt 4.19 kernel.
See full pull request [1] and NAND driver patch [2]
It would be a shame if duplicate work has been done.
Greats,
René
