The SEC block is internal to the LS1043. This is a hardware accelerator for the various encryption/decryption algorithms. It is configurable through software. It is located in the SoC.
1) Need to know if there are any pins or anything else that a custom board needs to be concerned with for the SEC engine?
2) No custom board changes are required for secure boot or the Trust Zone, is this correct?
3) If hardware custom board changes are required, what are they?
