20:01 <digetx> jonasschwoebel[m: in order to wake cpu core, the flow controller should unhalt it, the cpu clock needs to be on, cpu shouldn't be held by reset controller and the boot vector address should be set up

20:06 <digetx> you can add a PMC register write for resetting SoC to the reset handler of the secodary cores; if you'll get the restart on cpu core wake, then it works

20:07 <digetx> also see https://elixir.bootlin.com/linux/latest/source/arch/arm/mach-tegra/reset-handler.S#L145 where cpu cores skip erratas when TF firmware presents

20:09 <digetx> touching those regs with enabled secure world results in a halt
