Okay. While we are adding a target with a different (yet similar) CPU
JH7110S, I have questions about if we can also make JH7100 a variant
here too. How much difference is allowed for one U-Boot board target?

It would be great to have a single U-Boot target
starfive_jh71xx_defconfig for example. I am aware that mainline Linux
kernel defconfig can boot on JH7100 but some peripheral drivers do not
work correctly, and so there is a requirement to compile Linux kernel as
non-portable [1]. However I want to know what prevents U-Boot from
supporting all of JH7100, JH7110, JH7110S, with the same build target?

Anyways, this change to CONFIG_OF_LIST is sorted correctly and looks
good to me.
