From: Jeff Kletsky <git-commits at allycomm.com>
generic: Add/rename patches for consistency
ipq40xx: Generic-level patch replaces same-source patches-4.19/
082-v4.20-mtd-spinand-winbond-Add-support-for-W25N01GV.patch
Several SPI NAND chips were added between 4.19 and 5.1
including GigaDevice, Toshiba, and Winbond.
A fix to Macronix chips' ECC was also included.
* Add support for GigaDevice GD5F1GQ4UExxG
* Add support for all Toshiba Memory products
* macronix: Fix ECC Status Read
* add support for GigaDevice GD5FxGQ4xA
* Add initial support for Toshiba TC58CVG2S0H
* winbond: Add support for W25N01GV
The following two commits from 5.0 appear already backported upstream
so are not included here:
* Fix the error/cleanup path in spinand_init()
* Handle the case where PROGRAM LOAD does not reset the cache
Existing GigaDevice patches reordered to maintain upstream content
Upstream patches refreshed against 4.19.48
Build-tested-on: ipq40xx with TESTING_KERNEL enabled (4.19)
Run-tested-on: ath79/nand (4.19.48, WIP)

+Subject: [PATCH 1/8] mtd: spinand: winbond: Add support for W25N01GV
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.
