27  * Note on PKCS#11 TA commands ABI
28  *
29  * For evolution of the TA API and to not mess with the GPD TEE 4 parameters
30  * constraint, all the PKCS11 TA invocation commands use a subset of available
31  * the GPD TEE invocation parameter types.
32  *
33  * Param#0 is used for the so-called control arguments of the invoked command
34  * and for providing a PKCS#11 compliant status code for the request command.
35  * Param#0 is an in/out memory reference (aka memref[0]). The input buffer
36  * stores serialized arguments for the command. The output buffer store the
37  * 32bit TA return code for the command. As a consequence, param#0 shall
38  * always be an input/output memory reference of at least 32bit, more if
39  * the command expects more input arguments.
40  *
41  * When the TA returns with TEE_SUCCESS result, client shall always get the
42  * 32bit value stored in param#0 output buffer and use the value as TA
43  * return code for the invoked command.
44  *
45  * Param#1 can be used for input data arguments of the invoked command.
46  * It is unused or is a input memory reference, aka memref[1].
47  * Evolution of the API may use memref[1] for output data as well.
48  *
49  * Param#2 is mostly used for output data arguments of the invoked command
50  * and for output handles generated from invoked commands.
51  * Few commands uses it for a secondary input data buffer argument.
52  * It is unused or is a input/output/in-out memory reference, aka memref[2].
53  *
54  * Param#3 is currently unused and reserved for evolution of the API.
