We are not using OS but we will be using starterware. So What I have understood is that on power on I will hard reset eMMC reset line to active low through a GPIO and will not touch it anywhere after that and use the GPMC lines for NOR Flashing and Booting as well through starterware.I hope i have understood gerald.
I do not need eMMC for my requirement as of now. Rather I will use my custom board / custom cape on expander header with two chips one OTP and other parallel NOR Flash controlled by CSn0 and CSn1 and used for storing boot program and application software respectively. OTP will test the content of NOR Flash [checksum] and then application will be executed from NOR.
