+Subject: [PATCH] Allow --enable-psci to choose between smc and hvc
+
+According to Armv8-R AArch64 manual [1], Armv8-R AArch64 does not
+support smc:
+
+- Pseudocode for AArch64.CheckForSMCUndefOrTrap has this snippet:
+
+ if !HaveEL(EL3) || PSTATE.EL == EL0 then
+ UNDEFINED;
+
+ And Armv8-R AArch64 does not have EL3.
+
+- In the document of HCR_EL2 TSC bit:
+ If EL3 is not implemented and HCR_EL2.NV is 0, it is IMPLEMENTATION
+ DEFINED whether this bit is:
+ - RES0.
+ - Implemented with the functionality as described in HCR_EL2.TSC.
+
+So hvc is needed in this situation. And due to the lack of libfdt, the
+psci method cannot be modified at runtime.
+
+To use smc, use --enable-psci or --enable-psci=smc.
+To use hvc, use --enable-psci=hvc.
