Detailed Description

Low-level KMU HAL library.

Low-level HAL for provisioning, pushing, blocking, revoking, and querying KMU slots.

Provides functions to provision, push, block, and revoke KMU slots, read slot metadata, and check whether a slot is empty.

Note: These APIs are for internal use only. Applications must use the PSA Crypto API (psa_* functions) instead of calling these functions directly.
