I'll point it out here rather than Simon. As part of
https://github.com/open-source-firmware FIT is a standard and not "boot
loader specific". And one of the points of a FIT image is that you can
easily support multi-platform kernels in a single file (without
optimizing things further, at a cost in tens of milliseconds on a Pi 3
anyhow) and with user-controlled security.
