Yes, it could be a hint about the use case of this field.
Of course we could be more complete and also comment the umc field use 
in this same structure that depends on the family higher or lower than 
17 too.
But I had the impression that the creation of a new dram_type cache 
field would be clarified by a comment on the old location, that's it.
It's up to Yazen and you to include or not  this small addition about 
dram_type.
