Hi Konrad,

Shall I enable all platforms in one patch or in separate patches.

Reason why I am asking is if I enable controller and phys on cqs 
platform in patch -2, then cqm and iqs will have controller enabled, but 
not phys causing inconsistency in those platforms if only the patch-2 
would be applied.

Regards,
Krishna,
