| |
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.
