This patch series is modifying the existing CAAM driver to caam driver model. And is common caam implementation for all i.MX, Layerscape and powerpc. We already have blob encap/decap support added in cmd/blob.c After this patch series, We are also planning to add more feature for blob and command for derive_blob_kek later.
