The tester registers provide a unique chip-level identifier which get_board_serial() returns in a "struct tag_serialnr". This patch documents the properties of the registers; in summary. 31:0 OCOTP_TESTER0 (most significant) - FSL-wide unique, encoded LOT ID STD II/SJC CHALLENGE/ Unique ID OCOTP_TESTER1 (least significant) 31:24 - The X-coordinate of the die location on the wafer/SJC CHALLENGE/ Unique ID 23:16 - The Y-coordinate of the die location on the wafer/SJC CHALLENGE/ Unique ID 15:11 - The wafer number of the wafer on which the device was fabricated/SJC CHALLENGE/ Unique ID 10:0 - FSL-wide unique, encoded LOT ID STD II/SJC CHALLENGE/ Unique ID The 64 bits of data generate a unique serial number per-chip.
