Add support for v8M and in particular the security extension to the exception entry code. This requires changes to: * calculation of the exception-return magic LR value * push the callee-saves registers in certain cases * clear registers when taking non-secure exceptions to avoid leaking information from the interrupted secure code * switch to the correct security state on entry * use the vector table for the security state we're targeting Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 1506092407-26985-13-git-send-email-peter.maydell@linaro.org |
