[PATCH] mtd: spinand: winbond: Add support for W25N01GV

[Robert Marko]

W25N01GV is a single die version of the already supported
W25M02GV with half the capacity. Everything else is the
same so introduce support for W25N01GV.

Datasheet:http://www.winbond.com/resource-files/w25n01gv%20revl%20050918%20unsecured.pdf

Tested on 8devices Jalapeno dev board under OpenWrt running 4.19-rc5.

Hi Robert,

Please Cc the NAND mantainers when you send a NAND related patch
(in case you don't know about it already, scripts/get_maintainer.pl
should help you find who to Cc).
