Original code was a nested if statement for checking 1g() and
2g().https://github.com/TechNexion/u-boot-tn-imx/blob/tn-imx_v2021.04_5.10.72_2.2.0-stable/board/technexion/pico-imx7d/pico-imx7d_spl.c#L106Do
you have any information about the PCB layout of the different i.MX7 pico SoM
revisions?Question is, what is the electrical states of GPIO1_12 and GPIO1_13
in real for these variants? My fear is that maybe one of them is not connected
to any VDD (high) or GND (low). Question can be, what is the default logical
state for it high or low if one of them is not connected neither to GND or VDD?
I totaly do not understand why you need to completly refactoring the code if
you have no posibbilites to test it with all revision of SoMs. I rather prefere
to keep the original if statement code from Technexion, because that should
works 100% and tested. I have no any 2GB varians SoMs yet, also i can not test
it yet.So i am prefering more to apply my last (copy pasted from Technexion)
patch, to support 2GB SoMs in u-boot
mainline.https://lists.denx.de/pipermail/u-boot/2022-December/502465.html--------

board/technexion/pico-imx7d/{spl.c => pico-imx7d_spl.c} (83%) Could you please
test whether the attached patch works for you? I don't have a 2GB board variant
here to test it myself. You also need to apply the following patch to fix the
boot against U-Boot top of tree:
