If SPI_NOR_QUAD_READ is given, the driver assumes the chip supports Quad Output Read (1-1-4, 6Bh) and Quad Page Program (1-1-4, 32h). Except en25qh128, those chips don't support 1-1-4 read/program per datasheets. They do support Quad I/O Read (1-4-4, EBh). If you want to enable it, write fixup otherwise just drop the SPI_NOR_QUAD_READ flag, please. Thanks, Takahiro
