From c1547bba7eead64575a662acd95a986ac2956213 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 14 Jul 2022 14:22:59 +0100 Subject: [PATCH] target/arm: Fold regime_tcr() and regime_tcr_value() together The only caller of regime_tcr() is now regime_tcr_value(); fold the two together, and use the shorter and more natural 'regime_tcr' name for the new function.
