I would like to create a generic U-Boot build that adapts itself completely based on the DT passed in. That way we can potentially support running random board configurations with a single U-Boot binary built as part of the distribution.
Currently a few things are still missing to make it a full reality. The most obvious one I think is the EEPROM location. This would need to also move into something described by DT.
Apart from that, we're almost there. This patch adds a defconfig that simply contains all drivers we could make use of. We can then enable individual boards along the way and slowly adapt everything to be fully DT described while we identify each missing bit.
