yes, they are the same signal. the only difference is that VCC3V3 is
turned on later in the power-up sequence

I cannot see any of the TFLASH_* regulators being linked to eMMC (they
are only linked to the SD card slot, I also checked
odroid-c2_rev0.2_20151218.pdf and odroid-c2_rev0.2_20171114.pdf).
which page of the odroid-c2_rev0.2_20151218.pdf schematics shows how
TFLASH_VDD is linked to eMMC?
please note that I don't have an Odroid-C2 board myself (so I cannot
test any of this).
