I would say just go ahead with the new solution. AFAIK Aspeed
has pretty tight control over what kind of userspace run on these
systems.

BTW please influence Aspeed to use the GPIO character device
and ligpiod
https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/
if you are doing any kind of userspace GPIO control (which I
suspect that you do).
