As discussed a lot in the past, the UBWC config must be coherent across a number of IP blocks (currently display and GPU, but it also may/will concern camera/video as the drivers evolve).
So far, we've been trying to keep the values reasonable in each of the two drivers separately, but it really make sense to do so, especially given certain fields (see [1]) may need to be gathered dynamically. This series introduces a Single Source of Truth (SSOT) database to be consumed by multimedia drivers as needed.
