nit: Now that these messages become more visible you could consider making the
order a bit more consistent/hierarchical. Not sure what is the product ID vs.
the SoC ID (product is a variant of the SoC?). IMO it would make sense to
start with HW information, going from more generic to more specific, then do
the same for firmware.

  SoC ID
  Product ID	  // assuming this is a variant of the SoC
  ROM version
  Patch version	  // assuming this is a patch of the ROM firmware (?)

Sorry if I got any of the concepts wrong, from the names they are not entirely
clear to me.

In any case it's just a suggestion, feel free to ignore.
