Input buffer
An array of STORAGE_RPMB_DATA_FRAME structures.
Input buffer length
A multiple of sizeof(STORAGE_RPMB_DATA_FRAME). InputBufferLength / sizeof(STORAGE_RPMB_DATA_FRAME) indicates the number of input frames.
Output buffer
An array of STORAGE_RPMB_DATA_FRAME structures.
Output buffer length
A multiple of sizeof(STORAGE_RPMB_DATA_FRAME). The number of frames included can be calculated by OutputBufferLength / sizeof(STORAGE_RPMB_DATA_FRAME)
