But certain early SWs like bootloader which run before Device Manager is fully up would need to directly configure these registers and thus require to be in DT description. This add bindings for the cfg region and also adds them to DT files. Backward compatibility is maintained to existing DT by only mandating existing regions to be present and this new region as optional. Nishanth: I am hoping its possible for you to take bindings and DT via k3-dts-next once reviewed.
