Hi Romain,

Just a remark that is not directly related to your work: when people
take the time to review your work, try to keep them in Cc of the
following versions of your patchset.

Overall, it looks good to me (even if I don't fully agree on how you
decided to define NFC_SR_RB_EDGEX values :-P, but that's just a
nitpick).
