Actually MtBryce is the 5G personality on top of a given eASIC DM5, eASIC can be seen as process/fab technology.
Other eASIC chips != MtBryce. 
ACC100 == MtBryce literally, only usage is 4G/5G FEC as exposed by bbdev
Vista Creek is user friendly name for N3000 (Card + Arria10), these names tend to stick long after early deployments. 
I think it helps to include it in that doc as a one liner, even if through the rest of the doc and code the device is referred to as ACC100.
