AM3358: Secure boot information

Hello,

We are designing device based on BeagleBone Black with AM3358 on board.

We would like to secure our software, so we started to look for guides and application notes. 

We found 2 main guides:

• Enable security and amp up chip performance w/ hardware-accelerated cryptograpy (Rev. A)

• Secure Boot on embedded Sitara™ processor

But we need more detailed information.
