/* Spansion -- single (large) sector size only, at least
First chip reads Pm25LD020 or Pm25L0020. Found on some WD HDD PCB. Identified as PMC Pm25LD020. Flash read does not return consistent data which explains why the disk died. Second chip reads something like 25Q41BT. Found on Esspif ESP8266 based ESP-01 board. Identified as Elm Techchnology GD25Q41B. Datasheet is not clear about block size so erasing blocks may not work as expected.
