Lots of interesting information, especially these discussions where Alexander Graf chipped in:
The hand off of the boot loader to the actual OS payload. The payload and U-boot are in memory running at the same time. The payload can call back into U-boot through the uEFI API that U-boot implements so that the payload provides extra drivers enabling for instance a subsequent graphical stage (splash screen, menus, etc), more hardware access and so on. You even could pass ACPI tables through U-boot to the payload and help shooting yourself in the foot.
Important aspects for upstreaming:

Launch dates:
Now you only need a memory card and a camera module to make a nice “CCTV” system with plenty of choice. More details here:
Depending on what and when you record video, you might want to consider an IR capable camera. In Raspberry Pi land, they call them NOIR (which stands for No IR, meaning they leave out the IR filter which means they can record IR).

Very cool video based on these logic gates made from domino bricks:
The 4-bit calculator worked.
The 5-bit was set-up failed in part. That conclusion is at around 19:00.
A post mortem is at around 20:00: the machine was setup sizing it too small so the timing was too tight and didn’t work out.

I never realised that Amazon Alexa has an open source account on GitHub: https://github.com/alexa
There are full instructions on getting a Java based Alexa Voice Service (AVS) – also used by Amazon Echo – to run on a Raspberri Pi (3 or better recommended, works on 2 as well) with this extra hardware:
Full instructions are at Raspberry Pi · alexa/alexa-avs-sample-app Wiki and a video is below: https://www.youtube.com/watch?v=baec1CbV6A0
I should find some time to try this out (:
