Subject: [PATCHv2 0/2] mtd: m25p80: restore the addressing mode when stop using the flash
Date: Tue, 5 Dec 2017 13:33:20 +0800 [thread overview]
Message-ID: <20171205053322.35823-1-Zhiqiang.Hou@nxp.com> (raw)
From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>
To be compatible with legacy device, reset the addressing mode
to the default mode. Such as Freescale eSPI boot, it copies the
images from SPI flash without firing a reset signal previously,
so the reboot command will fail without reseting the addressing
mode of SPI flash.
