- * CPC field description
- *
- * req          is a command ID
- * result       is the status as returned by uC. If the communication to uC was
- *              not successful, this value will be set by the host
- * len          is the byte indicating how many bytes in data are valid data
- *              For read, this tells the kernel what is the expected size of
- *              data which will be returned by uC
- *              For write, this tells the kernel how many bytes in the data
- *              field are valid data.
- *              The range of this is 0 < n && n <= CPC_MAX_DATA_SIZE
- * nonce        is the counter which will be used for HMAC calculation. It is
- *              also used to correlate the response to the request. Host
- *              uses this value to match the response and the request
- * write_counter
- *              The counter which indicates how many successful commits have
- *              been made by uC for the life time of uC
- * data is the field which the client of uC could use to send / receive
- *              data which will be stored permanently by uC.
- * derivation_value
- *              This field should be used to pass the unique data during
- *              read counter, which will be used for encryption later by
- *              both parties
- * HMAC is the field which the client of uC could use to authenticate
- *              packets sent to and received from uC. If this field does not
- *              match uC's expectation, the packet will be rejected.
- *              HMAC is sent last tegra=>uC
- *              HMAC is sent first uC=>tegra
