Adam, I'm looking at your patches as I'm also trying to strip down the imx8mm-venice SPL so that I can fit DM USB support. It seems that all/most of the imx8m boards have a spl_board_init() which calls arch_misc_init(). I'm curious why your not calling that function? Another config that I've found to save a lot of space for imx8m without any negative impact I can see is CONFIG_SPL_MMC_TINY=y Best Regards, Tim
