Hi Simon,

U-Boot provides a verified-boot feature based around FIT, but there is no standard way of implementing it for a board. At present the various required pieces must be built up separately, to produce a working implementation. In particular, there is no built-in support for selecting A/B boot or recovery mode.
This series introduces VPL, a verified program loader. Its purpose is to run the verified-boot process and decide which SPL binary should be run. Adding VPL into the boot flow provides a standard way of implementing verified boot. So far, only the phase itself is added. More work is needed to add logic to the phase, based on continuing discussions about how best to standardise this feature.
This is quite interesting. Where is that data stored which SPL should run? fallback options? Do you have any proposal/document which describes it?
It is not quite ready for release. But I could talk about it on the U-Boot call next week if that suits.
