I am seeing the notice "Do not release JR0 to NS as it can be used by HAB" in SPL.
However, I do not understand what this means. I believe it has something to do with the Arm Trusted Firmware but I do not understand what I am supposed to do with this information or if it can be ignored.

I found the message is being printed in imx8m_caam.c
/* config CAAM JRaMID set MID to Cortex A */
if (mmio_read_32(CAAM_JR0MID) == HAB_JR0_DID) {
NOTICE("Do not release JR0 to NS as it can be used by HAB\n");
} else {
mmio_write_32(CAAM_JR0MID, CAAM_NS_MID);
}
