Multiple. You need to make sure that u-boot boots you non-secure
(there's no hyp-mode on the secure side). u-boot needs to be enabled for
that functionality. It hopefully is.
Make sure to use the uimage variant and boot with bootm.
Also set "setenv bootm_boot_mode nonsec" to override a possible wrong
default for this case here. Does this help already?

I've tried unsec boot mode, but second core doesn't start. I guess this is also something with the switch to hyp stuff. 

Is it possible to have "detached" threads (like l4linux ones) on this linux ?
