66AK2G12: reset and boot mode

Hello

below are my qurie

In our current design we are interfacing all our interfaces to 66AK2G12ABYA100E, but in evaluation schematics we see that the Keystone processor is being interfaced and controlled by TM4C129XNCZADI3 MCU known as BMC in evaluation schematics.

1. As per our customer requirement we are designing Processor board 66ak2g12 independent of BMC device , for this we wanted to understand significance of each signal, how can we implement the required  signals independently of BMC device.

2. How can we implement the BOOT Mode configuration in SOC? Presently in evaluation board it is taken care by BMC.
   we see bootmode 15:0 in soc pins ,we  can use bootmode 3:0 for boot mode selection with a switch ,what to do with rest 15:4 boot mode pins

3. How to Implement manual Resets (system rest, power on reset), In evaluation board it is taken care by BMC
   ,what should we do with NMLn,Resetn pin,RESETFULLn pin,PORn pins

4. Wanted to understand what are  the Operations performed by BMC device in evaluation board.
