Hi Catalin and Will,

I noticed that the following commit implement reboot via. PSCI SYSTEM_RESET
function. So my question is how to handle the reboot arguments?


What reboot arguments do you want to handle ?


static void psci_sys_reset(enum reboot_mode reboot_mode, const char *cmd)
{
invoke_psci_fn(PSCI_0_2_FN_SYSTEM_RESET, 0, 0, 0);

How to pass cmd to secure firmware?


What cmd do you want to pass ? The function id is already handled. What
else do you want to pass ?

If you see PSCI v0.2 spec, the SYSTEM_RESET and SYSTEM_SHUTDOWN takes no
parameters.
