Naive question I have not been able to answer by thinking a lot and reading the docs:
<Raito_Bezarius>
Is there a way to place FIT on a boot partition and let U-Boot (which can be inside firmware or whatever) load it for booting purpose?
<Raito_Bezarius>
I'd even go further: is there A/B semantics for FIT somewhere?
<Raito_Bezarius>
(or is it just store a recovery FIT inside the binary and have a custom FIT being loadable from some user controlled partition)
<Raito_Bezarius>
ah that's OF_CONTROL
<Raito_Bezarius>
Ah I suppose runtime FIT images on disk are handled via scripts per board and A/B can be implemented by flashing a recovery FIT on the disk I imagine
<marex>
Raito_Bezarius: you mean like, load fitImage from storage using 'load' command, and then 'bootm' it to boot it ? or source a script from it using 'source' command ?
<marex>
Raito_Bezarius: you can obviously do load $loadaddr mmc 0:1 boot/fitImage || load $loadaddr mmc 0:2 boot/fitImage , if load from first partition fails, try the second partition

sjg1: as I see you are the one driving the VBE specification, may I ask if you have plans to make it usable in any form for non-embedded systems like desktop systems?
<marex>
Raito_Bezarius: why ?
<Raito_Bezarius>
More specifically, I am curious if a FIT could induce a menu like extlinux-compatible config files
<marex>
fitImage is a container format , for packing in multiple files/configurations into single bundle (=file)
<Raito_Bezarius>
marex: it's unclear to me how it works with FIT signatures

Raito_Bezarius: the whole fitImage is signed, the bootm command triggers authentication
