The DT data has changed between the non-upstream data that people developed against previously, vs. the DT data that just went upstream here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=72296bde4f4207566872ee355950a59cbc29f852 and https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c35f1b87fc595807ff15d2834d241f9771497205 So Upstream U-Boot is going to need several patches to get things working again. Clock identifiers and Ethernet are two known areas. - Paul
