The Security Controller (SCC) is found on (at least) i.MX25 SoCs.
It is not a crypto engine in the usual sense. The only supported
algorithm in hardware is 3DES and the key is not configurable, but
is fused in the hardware.
The SCC can be handed some block of data in the red memory space
and it will return the encrypted data in the black memory space and
vice versa.
The API for this driver are the functions
- mxc_scc_cbc_des_encrypt
- mxc_scc_cbc_des_decrypt
Along with this driver a blobgen implementation is provided.
