Hi,
I'm trying to use SPL_OF_CONTROL with u-boot,dm-spl So I've marked u-boot,dm-spl with pinctrl since MMC used the pinconfig.
The issue observed here is SPL handover to U-Boot proper and before relocation U-Boot probed imx_thermal dm-driver through device_probe. But the same time device_probe unnecessary probing all u-boot,dm-spl marked nodes(which are strictly related for SPL) Since pinctrl marked as u-boot, dm-spl the same probed and this might be the show-stopper.
Based on the data abort, the code hang at relocation code, relocate.S, eventually stop calling uclass_get_device( was called in arch/arm/mach-imx/cpu.c) during board_f or unmark u-boot,dm-spl make U-Boot boots.
Below are relocation code hang point and Log dump, request for any inputs.
Relocation code: ----------------------
