Every now and then someone wants to chain-load U-Boot on a
Chromebook.
The procedure is not very complicated but there are some oddities.
This series updates a few things with allow U-Boot to start on nyan-big in this way and adds documentation on how to do it. This provides a central place where the procedure on different devices can be
documented.

Thank You for this Simon! Very much appreciated! I am going to give this a try later tonight and report back my personal results...

Confirmed! Chain-loading working on my nyan_big. I appreciate this very much Simon and all who contributed.
I'd like to pull in this series. Are there any comments / reviews? If affects both tegra and rockchip.
I'm fine with it - I assume you'll pull it in to one of your repos and post a PR to get it into mainstream U-Boot? I don't have the HW to test on (my nyan-big has been shelved), but trust in Matthew's testing, and that Stephen's U-Boot test scripts will catch any problems, so LGTM.
Tom
Regards, Simon
