There is a fix required in BBL for real board. We have not send
this fix to riscv-pk.

BBL does not set "stdout-path" in /chosen DT node so you are not
seeing any output from U-Boot on real board. On QEMU, "stdout-path"
is set in DTB by QEMU itself so we don't see any issue on QEMU.

We typically run OpenSBI+U-Boot on real board and OpenSBI sets
"stdout-path" properly before jumping to next stage (i.e. U-Boot) so
even we don't see this issue at our end.

You can easily hack BBL for above fix at your end.

Anup
