From: Aidan <[email protected]> Add #include <linux/types.h> to include/hash.h so that basic types (u8, u32, etc.) are available to all includers.
Add a wc_Sha384Hash() wrapper declaration in include/hash.h, gated by WOLFTPM2_NO_WOLFCRYPT. When wolfTPM is built without wolfCrypt, this wrapper provides SHA-384 hashing via U-Boot's hash subsystem, which is needed for Infineon TPM firmware update manifest validation.
