## Detailed Description

Css driver.

This component abstracts the hardware access to the CSSv2 IP. The library exposes the following hardware functionality:

1. COMMON
   - CSSv2 Software Reset
     - mcuxClCss_Reset_Async
2. HASH
   - SHA-2 hashing
     - mcuxClCss_Hash_Async
   - SHA-2 hashing in direct mode
     - mcuxClCss_Hash_ShaDirect
3. CIPHER (Symmetric Encryption)
   - AES
     - mcuxClCss_Cipher_Async
4. KEY MANAGEMENT
   - Key import
     - mcuxClCss_KeyImport_Async
5. ECC (Elliptic Curve Cryptography)
   - ECC Key generation
     - mcuxClCss_EccKeyGen_Async
   - ECC signature generation
     - mcuxClCss_EccSign_Async
   - ECC signature verification
     - mcuxClCss_EccVerify_Async
6. KEY DERIVATION
   - Key derivation

After each call to a function ending in `_Async`, one of the waiting functions mcuxClCss_WaitForOperation or mcuxClCss_LimitedWaitForOperation must be called to ensure completion. The waiting functions may fail, e.g., when the CSSv2 enters an error state.
