Which pin is "GPIO_3 pad" described in Section 6.6.11 USB low-power boot for i.MX7D reference manual?
How can the "GPIO_3 pad" be chosen?

There was a change in 7D ROM that it altered LPB from GPIO1_3 to GPIO1_2. So, the pad is GPIO1_2.

Is this change documented anywhere? I haven't found any updated specs or errata. I am completing a design that would benefit from Low Power Boot support and want to make sure I get it right.
