Currently the support for maximum key size supported in HMAC hash
functions is limited by the underlying Global TEE implementation.
The RFC 2202 and 4231 specify some HMAC test vectors where key size
is greater than the sizes as supported in current TEE implementation.
For such key sizes, greater than the maximum key size supported by TEE,
first hash the key and then use the resultant as the actual key to
HMAC.
