The 35h instruction op code has two aliases/macro definitions: - SPINOR_OP_RDCR from include/linux/mtd/spi-nor.h - SPINOR_OP_RDSR2 from drivers/mtd/devices/serial_flash_cmds.h Actually, some manufacturers name the associated internal register Status Register 2 whereas other manufacturers name it Configuration Register hence the two different macros for the very same instruction op code. Since the spi-nor.h file is the reference file for all SPI NOR instruction op codes, this patch removes the definition of the SPINOR_OP_RDSR2 macro. Also the SPINOR_OP_RDSR2 macro will be associated to another instruction op code in a further patch so we need to avoid a conflict defining this macro twice. Indeed the JESD216 rev B specification, defining the SFDP tables, also refers to the 3Eh and 3Fh instruction op codes to write/read the Status Register 2 on some SPI NOR flash memories, the 35h op code still being used to read the Configuration Register/Status Register 2 on other memories.
