We're not going to see pre-A3 chips in > production systems. We should split this patch into two. The A3 support is not yet present in any u-boot tree, so it would be premature to update any socs to emulate the A3. We can expect support in the coming months, and when that lands we can consider updating. However filling out some of the clock register reset values is important for guests to calculate sensible clock rates, so we should do that now for the A1. Cheers, Joel
