Dear NXP team.
I have some question how to control CAAM H/W.
I have ls1021A-IOT board and i.mx6qsabreauto.
LS1021A-IOT board boot and CAAM work well with non-secure mode .
And i.mx6qsabreauto board boot with secure mode. So i changed linux kernel to boot with non-secure mode.
of course, modified the CSU_CSL17(CAAM) register to 0x00ff00ff so that CAAM can be accessible in both non-secure and secure worlds.
But CAAM is not working and I can not see value of caam register in non-secure mode . all of them(caam register values) are 0.
I really don't know why and what i should modify...
I could see ls1021x_config_caam_stream_id() code in u-boot code of ls1021a-iot.
1. I also need to add kinds of ls1021x_config_caam_stream_id() for i.mx6qsabreauto?
2. could you explain about ls1021x_config_caam_stream_id()?
Have a great day.
