FYI, I have build- and runtime-tested this series on i.MX25/35/51/6, and build-tested it on mpc512x.
Note that the original OCOTP driver from Freescale has several bugs in the function setting the timing register: - It sets tRELAX to 15.2 ns although it should be > 16.2 ns (for 66-MHz IPG clock). - It uses DEF_RELAX instead of relax to set strobe_prog/read, i.e. it mixes ns with IPG clock cycles. The result is tPGM = 10.6 µs instead of 10 µs (but 9 µs < tPGM < 11 µs is still satisfied), and tRD = 636 ns > 36 ns. So just by chance, this does not break the hardware behavior. - It unexpectedly clears the WAIT bit-field, which has a non-zero reset value.
