Same here. On top of that the bloblist has a few items in there, e.g a TPM eventlog. What are we going to do? Add a Kconfig for each item? This has been going back and forth for a while. I've lost count of how many times I repeated the same proposal, but here it goes again. We have OF_BOARD and BLOBLIST options. The bloblist and its properties are scannable at runtime. Can't we use the combination of these 2 can be used to imply we expect things from a bloblist. If we want to be stricter in the future and explicitly expect the DT from a bloblist, we could add a Kconfig option failing the boot if that's missing. Thanks /Ilias > > -- > Tom
