35  * We can't use XEN version here, because of SMCCC requirements:
36  * Major revision should change every time SMC/HVC function is removed.
37  * Minor revision should change every time SMC/HVC function is added.
38  * So, it is SMCCC protocol revision code, not XEN version.

40  * Those values are subjected to change, when interface will be extended.
