Should MCUBoot provide hooks into TLVs?

[JPHutchins]

I can use the existing hooks to read TLVs from an image. Haven't tried, but why not?

Should MCUBoot provide hooks to these that would be less error prone than "I know what I'm doing"? Like it would pass a pointer to the first TLV so that the user can easily iterate through theme?

Presently thinking about encoding information about supported HW reversions and variants in custom TLVs.
