The patches all look sane, so +1 from me.

The one thing that worries me is I'm not sure "soc" or "board" are ever *meant* to be blank in the env, but I can't find anything to that effect in the docs/comments. Anyway, they evidently are in this case so the workaround's necessary.

100+
101+If the environment does not have "soc" or "board" set, and fdtdir
102+option is specified in extlinux.conf, the bootloader will crash whilst
103+dereferencing a null pointer. Add a guard against null soc or
104+board. Fixes a crash of qemu-riscv64_smode configuration, which does
105+not have CONFIG_SYS_SOC defined.
