clearfog_defconfig with: CONFIG_MVEBU_SPL_BOOT_DEVICE_SATA=y CONFIG_SPL_SATA=y Plus a dts patch to sdhci@d8000 to make it work for eMMC (swap cd-gpios for non-removable) Plus a workaround that's not yet merged for a build failure with SATA from [1] Shouldn't be anything that affects the timer, but I can try a fully clean build with the defconfig if you need it.
