Sorry for the slow review...

Hmm. I still tend to think we should list the specific SoC rather than
the family here, but I guess if you're sure there won't be any SW
compatibility between the different SoCs in the series, this is fine.

The most specific value should be first, so swap those two entries.

Should that be 11140 rather than 1140?

Aside from that,
