commitfdce9d35dc("arm: dts: am33xx: Sync dts with Linux 4.20.0") did remove the "u-boot,dm-spl" flag from the 'ocp' bus which was introduced with commit19aa4ac09d("dts: am33xx: add u-boot, dm-spl to ocp bus") Due to this all boards having CONFIG_SPL_OF_CONTROL enabled are broken because they cannot bind/probe the boot-media interface during SPL stage. This commit introduces the 'am33xx-u-boot.dtsi' which is included with the auto include mechanism. The am33xx-u-boot-dtsi adds the important "u-boot,dm-pre-reloc" to the 'ocp bus' (the root bus of almost all peripherals, at least the bootable ones). The peripherials (mmc, spi, ...) needed during SPL stage need to be equipped with the 'u-boot,dm-pre-reloc' in their responsible dts file.
