Sorry. Stupid outlook. Will take care of it manually.

By board I mean a new development board. 

New board
sysclk = 24MHz
codec_name = "tlv320aic3x-codec.1-001b"

Previous Board
sysclk = 12MHz
.codec_name = "tlv320aic3x-codec.2-001b",

Both boards share the same machine is API (machine_is_am33xx()).

So, is there any mechanism/api to differentiate these 2 boards inside 
Code?

Has anyone else faced such situation?
