Iglesias" , Paolo Bonzini , =?UTF-8?q?Alex=20Benn=C3=A9e?= , =?UTF-8?q?Andreas=20F=C3=A4rber?= Implement the asidx_from_attrs CPU method to return the Secure or NonSecure address space as appropriate. (The function is inline so we can use it directly in target-arm code to be added in later patches.) Signed-off-by: Peter Maydell Acked-by: Edgar E.
