Provide a mechanism to encrypt a red key using the KEK; the KEK is
only available on secured boards after the RSA_EN and PPK eFUSES have
been burnt (the system will only boot ROM authenticated bootloaders
from here on).
The main use case for OP-TEE would be to encode the zynqmp per device
unique identifier (DNA0, DNA1, DNA2 eFUSEs - ie, a red key) using the
KEK. The encryption key generated this way is cryptographically strong
and will be used as the device HUK (ie, black key).
Test code:
csu_aes_encrypt_data(src, dst, BLOB_DATA_SIZE, tag, GCM_TAG_SIZE,
iv, GCM_IV_SIZE, CSU_AES_KEY_SRC_DEV);
csu_aes_decrypt_data(dst, src, BLOB_DATA_SIZE, tag, GCM_TAG_SIZE,
iv, GCM_IV_SIZE, CSU_AES_KEY_SRC_DEV);
if (memcmp(src, buffer, BLOB_DATA_SIZE)) {
EMSG(" - encrypt/decrypt test failed");
