I second Gabe's suggestion. I think the IDE controller is a good starting point since it mostly models the controller and passes more complicated (device specific) functions to the disks. I mostly templated based on the IDE controller when we started adding a PCI interface for GPU (see WIP here: https://gem5-review.googlesource.com/c/amd/gem5/+/23485).
