I'd recommend testing the DT patches with BBL and the open-source FSBL.
That's the traditional way of booting RISC-V Linux systems.

The goal is to transition to U-Boot over time. However, right now the
U-boot port is still new. It wouldn't surprise me if we need to modify
the kernel, U-boot, or the SBI layers as part of that process. In the
short term, we need to get some sort of baseline DT data in place before
more chips and boards start showing up.

I'll post a separate message with details on how to reproduce the test
setup that I'm using.
