Could you help me in understanding what they have explained in cfg_rcw_src[6:7]? I could understand that for option 10 it provides upto 28b addressability which corresponds to 4Gb address locations for 16bit NOR and 2Gb address locations for 8bit NOR. 


I don't understand these words, " Shift left by 4 to provide up to 28b addressability OR shift right by appropriate amount
(depends on Port Size selected)" under option 10. could you explain me to understand it?
