[PATCH 0/2] mtd: spi-nor: add stm32 qspi driver

[Ludovic Barre]

From: Ludovic Barre <ludovic.barre at st.com>

This patch set adds a SPI-NOR driver for stm32 QSPI controller.
It is a specialized SPI interface for serial Flash devices.
It supports 1 or 2 Flash device with single, dual and quad SPI Flash memories.

It can operate in any of the following modes:
-indirect mode: all the operations are performed using the quadspi
 registers
-read memory-mapped mode: the external Flash memory is mapped to the
 microcontroller address space and is seen by the system as if it was
 an internal memory
