[oe] How to force recipe to be parsed eveey time - dynamic PV value

[Kubalski, Lukasz (EXT-Espotel - PL/Wroclaw)]

I have problem that recipe is not always parsed.
Is it way to force it? Like checksum/signature/stamp invalidation?

Problem details:
   I need to have my PV to be generated dynamically e.g like PV = "${@my_get_version_func(d)}"

In such case recipe is not parsed every time (checksum doesn't change), PV is no reevaluated  and even my_get_version_func would return different value my image is not rebuilt.

Thanks for any suggestions.
