[PATCHv2 0/2] mtd: m25p80: restore the addressing mode when stop using the flash

[Zhiqiang Hou]

From: Hou Zhiqiang <Zhiqiang.Hou at 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.
