MX8MN doesn't support dek blob length higher than 128Bits

We have successfully implemented u-boot encryption. We can encrypt and sign the SPL and the FIT of the u-boot with 128Bit dek blobs. But when we tried to use 256Bit the dek_blob command didn't worked.

Is their  any information about a dek blob size limit for the MX8MN?

Thanks,
