From: Ludovic Barre <ludovic.barre@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
