It's in very early stages. The rockchip series uses it and I believe
Marek is using it for socfpga.

You will need to add u-boot,dm-pre-reloc to your console node that
that the DT has that node. See u-boot-dm/rockchip-working for what
happens there. Use fdtdump on your u-boot-spl.dtb to check that it has
what is needed.

Also, enabling DEBUG_UART is a good idea.

Simon
