What exactly are you referring to?

This patch places in into the device tree and marks it as disabled,
but anyone not restricting the CAAM with secure mode functions
can mark it as enabled.

Even if - due to export control regulations - CAAM is "trimmed down",
it loses only the encryption capabilities (hashing etc. still working).

Again, please clarify what you mean by "secure mode functions",
"security features" etc.
