    mtd: gpmi: add gpmi support for imx6sx · 91f5498e
    Huang Shijie authored
    The gpmi's IP for imx6sx is nearly the same as the gpmi's IP for imx6q,
    except the following two new features:
    
         (1) the new BCH contoller has 62-BIT correcting ECC strength
                (The BCH for imx6q only has 40-BIT ECC strength).
    
         (2) add the hardware Randomizer support.
    
    This patch does the follow changes:
    
         (1) add a new macro GPMI_IS_MX6SX to represent the imx6sx's gpmi.
    
         (2) add a new macro GPMI_IS_MX6.
               We use this macro to initialize the same registers for both
             imx6sx and imx6q, and so on.
    
         (3) add a new gpmi_devdata instance, the gpmi_devdata_imx6sx, for
             imx6sx.
