You already have all relevant information present in the current
configuration. There is no need to add yet another CONFIG_SYS_
option; the information can easily be derived from the existing data.

Ernest asks Frank how long he has been working for the company.
"Ever since they threatened to fire me."
ISBC (Internal Secure Boot Code) is an IP which has different versions on
different SOC's. The major difference which this CONFIG represents is whether
CAAM block is being used for cryptographic operations or not. I will be adding
more details in the description IN README and resend the patch.
The only other way that this can be derived is by doing SoC specific checking
which would become a little messy.
