The schematic shows Gen3V3 is driven by sw2_reg on the pfuze100 PMIC. Linux doesn't appear to have an issue keeping this rail up, but U-Boot shuts it down for some reason.
This patch sets 'regulator-always-on' for sw2_reg to keept this rail powered.
Why does U-Boot shuts down sw2_reg?
sw2_reg has a consumer: &usdhc1, so it should keep turned on.
Or you don't use usdhc1 port in U-Boot?
Just want to understand this problem better.
