According to the Cypress datasheet, this memory part number supports Fast Read: - Dual Output (SPI 1-1-2) - Dual I/O (SPI 1-2-2) - Quad Output (SPI 1-1-4) - Quad I/O (SPI 1-4-4)

So you should also add the 2 flags SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ in addition to SECT_4K and also the flag SPI_NOR_4B_OPCODES since this part number also supports the 4-byte address instruction set.
Best regards,
Cyrille
