[PATCH v6 08/17] ARM64 / ACPI: Parse FADT table to get PSCI flags for PSCI init

2015-01-04 Thread Hanjun Guo
There are two flags: PSCI_COMPLIANT and PSCI_USE_HVC. When set, the former signals to the OS that the firmware is PSCI compliant. The latter selects the appropriate conduit for PSCI calls by toggling between Hypervisor Calls (HVC) and Secure Monitor Calls (SMC). FADT table contains such informatio
