It's detected by testing the 4BYTE operation capability in the SFDP table in mx25l25635_post_bfpt_fixups() The only system I have access to is a SuperMicro P9 Boston but I can not upload a new kernel. However, the FW reports : BMC flash ID: 0xc21920c2 jedec_id: 0xc21920c2 flash type: MX25L25635F ReadClk=0x32, WriteClk=0x85, EraseClk=0x85 [smcfw_spi] cpuclk: 198000000 MHz, RefCLK: 24000000 MHz, AXI-AHB ratio: 2:1 platform_flash: MX25L25635F (32768 Kbytes) > It's the one > that Alexander tried to get merged by renaming the mysterious > mx66l51235l. Yes. That one behaves a bit more like the mx25l25635e. Difficult to find a detection pattern. A model for SFDP would help.

The mx25l25635f is an extenstion of the mx25l25635e. It includes QPI support, 4-Byte Address Command Set and faster transfers. See this document for more details : https://www.macronix.com/Lists/ApplicationNote/Attachments/1892/AN0200V1_MGRT_MX25L25635E_25735E%20to%20MX25L25635F_25735F.pdf Both devices have the same 3bytes JEDEC ID: 0xc22019. They can be distinguished with the QPIID command which is only available on mx25l25635f. The mx25l25635f also has a longer JEDEC ID that we can use for the model.
