But, uh, this tells me some TI folks forgot to > backport all of the dts changes too then as we shouldn't have broken > platforms in-tree like this. In both Linux and U-Boot, the error (warning) message: RGMII mode without internal TX delay unsupported; please fix your Device Tree only indicates that the device-tree should be updated to use 'rgmii-id' instead of 'rgmii-rxid'. The functionality however remains unaffected. The current Linux device-tree patch is not really fixing an issue from a functionality perspective, and the same holds true for U-Boot. I realize however that a DT sync patch could (should) have been posted by me to the U-Boot mailing list after this patch had been merged to Linux instead of waiting for the periodic DT sync.
