Subject: [PATCH] [v3]mtd: spi-nor: winbond: add 1.8v SPI NOR Flash IDs
Date: Sun, 26 Apr 2020 11:24:10 +0800	[thread overview]
Message-ID: <20200426032410.10425-1-wuxy@bitland.com.cn> (raw)

From: wuxy <wuxy@bitland.corp-partner.google.com>

Winbond has new 1.8V SPI NOR Flash IDs,we need to use the SPI
flash ID in kukui series,this patch can support the new flash IDs.
This patch copied from:https://patchwork.ozlabs.org/patch/1150756/,
The original patch is invalid,so re-submit a new patch for this.

TEST=boot to shell,get the spi information from 'dmesg'.
