	  The Toradex config block stored production data on the on-module
	  flash device (NAND, NOR or eMMC). The area is normally preserved by
	  software and contains the serial number (out of which the MAC
	  address is generated) and the exact module type.

	  inside the Toradex vendor ID (0x1b67) the range starting from
	  offset 0x4000 is reserved for Colibri/Apalis modules.
