Hi all,
in the table in drivers/mtd/spi/spi_flash_ids.c there is a flag WR_QPP set against Macronix devices (including the ones Dumitru is just adding). This is used when programming the devices on a 4-bit bus to select the command to use for programming - either CMD_QUAD_PAGE_PROGRAM (0x32) or CMD_PAGE_PROGRAM (0x2). The Macronix devices that I have a spec for do not mention command 0x32. Each of the devices that I have a spec for ( MX25L25635F MX25U51245G MX25V8035F and MX25V1635F ) use command 0x38 instead. This would suggest to me that devices that support quad I/O, and have Macronix NOR-SPI, won't be able to program them. Am I missing something, or is this a problem? I'm not able to check because we don't use Quad I/O.
