They can be distinguished with the QPIID command which is only available on mx25l25635f and their Serial Flash Discoverable Parameters. However, some FW use the JEDEC ID. For instance, on a SuperMicro P9 Boston, the BMC 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) Define the mx25l25635f with an extended JEDEC ID.
