BDK will allow developers to use the full collection of drivers, with limited editing, if any, for making payloads for Nintendo Switch. Using a single source for everything will also help decoupling Switch specific code and easily port it to other Tegra X1/X1+ platforms. And maybe even to lower targets. Everything is now centrilized into bdk folder. Every module or project can utilize it by simply including it. This is just the start and it will continue to improve.
