I attempted switching to upstream OpenSBI and generic platform but I
could not get it to boot.  I do want to further troubleshoot that with
you but, for now, I did not feel it is that important in the context of
buildroot.

The urgency for this patch is to get buildroot pointing to the 5.13
kernel as it has fixes for several problems in the older 5.10 kernel
that buildroot currently points to.  A buildroot user looking at
upstream right now would not know that we have moved on to 5.13.

Another practical issue is that upstream OpensBI generates a much bigger
fw_payload.bin.out. Commit 2524b0e [1] in starfive-tech/opensbi makes it
easier for people doing uboot development as the xmodem transfer of
fw_payload.bin.out is much faster.

thanks,
drew
