I have few queries on CSEc module and secure boot. Can you please help me to understand below queries.
From below diagram I see PRAM(memory to store secure keys) is of 128 Bytes.
Is this memory extendible and configurable ?
What is the maximum number of keys we can store in this area ?
What is single secure key size in bytes?
To enable secure boot for certain memory region, I know we use BOOT_MAC_KEY_VALUE.
What key should we use if multiple memory regions need to be secured, whether it is same BOOT_MAC_KEY_VALUE ?
Once we enable secure boot(FTFC->FCSESTAT->BOK is 1), how to prove the secure boot concept ?, please guide me the steps.
