Thanks for working on this! Are you also planning on adding the
features of the FSBL to U-Boot to remove it from the boot flow?

I was able to run U-Boot and boot Linux successfully on a SiFive HiFive
Unleashed board with this patch series. I had to make one more change,
because U-Boot was not able to find a serial driver and paniced as a
result.

I fixed this by making the serial driver available pre-relocation. For
this, the soc compatible has to be added to cpu/generic/cpu.c and the
serial driver must have the DM_FLAG_PRE_RELOC flag set.

Another way would be to add a "stdout-path" property to the chosen node
of the device tree.

Thanks,
Lukas
