Peter Maydell a036c73de8 target/arm/psci.c: If EL2 implemented, start CPUs in EL2 The PSCI spec states that a CPU_ON call should cause the new CPU to be started in the highest implemented Non-secure exception level. We were incorrectly starting it at the exception level of the caller, which happens to be correct if EL2 is not implemented. Implement the correct logic as described in the PSCI 1.0 spec section 6.4: * if EL2 exists and SCR_EL3.HCE is set: start in EL2 * otherwise start in EL1 Backports commit 3f591a20221511c639cc7959755e570801a21cd2 from qemu		2018-03-01 23:34:57 -05:00

Clean/simple/lightweight/intuitive architecture-neutral API
Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal and Haskell.
Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
High performance via Just-In-Time compilation
Support for fine-grained instrumentation at various levels
Thread-safety by design
Distributed under free software license GPLv2
