Varun Wadekar cb790c5e48 Send power management events to the Trusted OS (TLK) This patch adds PM handlers to TLKD for the system suspend/resume and system poweroff/reset cases. TLK expects all SMCs through a single handler, which then fork out into multiple handlers depending on the SMC. We tap into the same single entrypoint by restoring the S-EL1 context before passing the PM event via register 'x0'. On completion of the PM event, TLK sends a completion SMC and TLKD then moves on with the PM process. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>	9 years ago
