I'm working on the ZC702 board and trying to boot Linux and Optee. My boot flow is:
Although Optee is booted successfully, Linux hangs on the 'zynq_early_slcr_init' function at booting.
Probably Op-tee OS locking down access the SLCR. So When Linux accesses SLCR, the system crashes.
How can I solve this problem?
