According to its datasheet, the Macronix MX25U25635F, like the MX25U3235F,
supports Fast Read 1-1-2 (3Bh) and Fast Read 1-1-4 (6Bh) hence both
SPI_NOR_DUAL_READ and SPI_NOR_QUAD_READ flags should be set too.
Also extracted from the datasheet:
"Equal Sectors with 4K byte each, or Equal Blocks with 32K byte each or
Equal Blocks with 64K byte each"
Sector Erase 4K (20h) is supported hence the SECT_4K flag.
Best regards,
Cyrille
