chewitt, you should know that I had better idea years back because I actually know how u-boot works on this SoC. But no one listen. And now I don't care anymore (but it still hurts after all this time).
It doesn't really matter how u-boot works. It was done the way it was because it can be the same for all supported SOCs. Likely this can be improved now to combine a few similar boards but it works well the way it does.
