Yes, this is part of the overhaul I'm working on, to allow runtime SFDP override static SFDP using predefined strategy from kconfig. |

In most of the multi-spi NOR flash, its SFDP table contains information about the PageProgram command support.
This information is reported by the jedec as:
PH4: ff84 rev 1.0: 2 DW @ 134
Question : could the parsing of the jedec SFDP table, replace or complete or overwrite the property given by the DTS property:
if the SFDP table indicates "Support Support for (1-1-4) Page Program Command, Instruction=34h" is supported then consider the write-io-mode property: "MSPI_IO_MODE_QUAD_1_1_4"
if the SFDP table indicates "Support for (1-4-4) Page Program Command, Instruction=3Eh" is supported then consider the write-io-mode property: "MSPI_IO_MODE_QUAD_1_4_4"
