All BLs have a bl_setup() for things that need to happen early, a fall back into assembly and then bl_main() for the main functionality. This was necessary in order to fiddle with PAuth related things that tend to break C calls. Since then PAuth's enablement has seen a lot of refactoring and this is now worked around cleanly so the distinction can be removed. The only tradeoff is that this requires pauth to not be used for the top-level main function. There are two main benefits to doing this: First, code is easier to understand as it's all together and the entrypoint is smaller. Second, the compiler gets to see more of the code and apply optimisations (importantly LTO).
