Wiki says "work in progress"

http://linux-sunxi.org/Mainlining_Effort
http://linux-sunxi.org/NAND (Fun facts on supported NAND)
http://linux-sunxi.org/MTD_Driver

https://groups.google.com/forum/#!searchin/linux-sunxi/mtd%7Csort:relevance

Boris has commit access so it's probably all there since 4.7

His work and derivatives did touch a lot of NAND/MTD drivers though.

Someone needs to crawl the linux kernel commits though or ask directly.
