WDYT?

WDYT? No, I don't see any good reason for doing so currently. You may be able to share a few pointers between some of the SoCs but only until it turns out they need to override certain sequences anyway (e.g. sc8280xp which mixes v4 and v5 tables currently). You'd also need dedicated aggregate table structs for USB and DP and it seems all of this would just make things more opaque for little gain. Johan

I was thinking about moving the qmp.*init_registers into the common library. However let's probably finish the cleanup before working on code consolidation.
