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 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.
