I will add the same comment here

Not necessarily, it can change, it used to change across GXBB boards, but
seems to be more coherent across GXL/GXM/G12A ref designs and derivative
boards, but it can still change if the HW designer decides to be creative !

I think VDDQ1_5 is specific to SEI510, will check on the schematics
