I assume it is good to document the fact that perhaps using dm-pre-reloc tag (and later boot-phase tag) will overcome many odd properties format in Linux DTS. We said dm-pre-reloc is a workaround, but IMHO the tags are really good for u-boot, since u-boot is a multi-phase boot loader. If a device like UART is needed in a certain phase, we should say so. Also at the moment, modifying the serial-uclass.c is something more than I can chew. If I must do it myself, it will be a while. If anybody wants to give it a try, please do so.
