Subject[Query] How to pass reboot arguments to secure firmware with PSCI spec
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?


> 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?

> }

Thanks in advance,
Jisheng

PSCI: Add initial support for PSCIv0.2 functions

The PSCIv0.2 spec defines standard values of function IDs
and introduces a few new functions. Detect version of PSCI
and appropriately select the right PSCI functions.
