From f785d59aaeadd4d8f1707f2c5fffcf143de9da2c Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 14 Dec 2015 17:36:22 +0000 Subject: target-arm: Implement asidx_from_attrs 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.)
