Boot: Secure ROM Panic due to Certificate Info not present

Details:

In normal boot flow ( other than Full Combined Image flow), if Certificate info ( Extended info or Legacy info ) is not present, Secure ROM will enter to an infinite loop. This condition will be observed when a certificate is given to the SOC, which has no certificate info present in it. Secure ROM will panic ( stuck in infinite loop ) on below further conditions:

  1. Certificate info is not present
  2. Address translation Failure
  3. Hash computation failure

Workaround(s):

Ensure that Certificate into is present (Extended info or Legacy info).
