In that case, these CLs (could be referred) need be landed.

CBI could set as in the end of 32bit FW_CONFIG.
1.	WFC - 3 bit (0: none-MIPI; 1: Kingcome 8MP; 2: TBD
2.	UFC - 2 bit (0: none-MIPI)   --> 0 since UFC is USB.

However, we should take Maglia as higher priority (not clarified yet). And leverage the same approach to Storo by copying exactly as its schedule is later.

Karthik, Henry, What do you think?
