From: Dave Jiang <[email protected]> Adding support code to simulate the enabling of LSS status in support of the Intel DSM v1.6 Function Index 10: Enable Latch System Shutdown Status. This is only for testing of libndctl support for LSS enable. The actual functionality requires a reboot and therefore is not simulated. The enable value is not recorded in nfit_test since there's no DSM to actually query the current status of the LSS enable.
