Simple enough,

Although I do question our use of the J7x names. All of our parts here
also have a "Sitara AMxx" branding. For instance here we could call
this new device by its "AM67" name, then J784S4 renamed as AM69, etc.
Then we would have a consistent naming (internally we will have to deal
with the part name madness, but why expose that externally if we don't
have to).
