Message-ID: <20140801180652.72e722be@xhacker> (raw)

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?

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.
