Subject: [PATCHv3 0/2] mtd: m25p80: restore the addressing mode when exiting

From: Hou Zhiqiang <Zhiqiang.Hou@....com>

Restore the status to be compatible with legacy devices.
Take Freescale eSPI boot for example, it copies (in 3 Byte
addressing mode) the RCW and bootloader images from SPI flash
without firing a reset signal previously, so the reboot command
will fail without reseting the addressing mode of SPI flash.

Hou Zhiqiang (2):
  mtd: spi-nor: add an API to restore the status of SPI flash chip
  mtd: m25p80: restore the status of SPI flash when exiting
