    spi: spi-mem: add stm32 qspi controller · c530cd1d
    Ludovic Barre authored
    The qspi controller is a specialized communication interface
    targeting single, dual or quad SPI Flash memories (NOR/NAND).
    
    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
    
    tested on:
    -NOR: mx66l51235l
    -NAND: MT29F2G01ABAGD
