I'm not too clear on what is happening here, but have you looked at SPL_HANDOFF or BLOBLIST?
Yeah, but these are not for our use case here. Our handoff are generated from the tool, which having user settings. Our secure device manager will pass these handoff to SPL, this driver is mainly for parsing our handoff format to consistent format in the table, which will be consumed and checking other drivers.
