From 4e42a6ca37e39e56725518851f4388e46bd91129 Mon Sep 17 00:00:00 2001 From: Sergey Fedorov Date: Mon, 15 Jun 2015 18:06:07 +0100 Subject: [PATCH] target-arm: use extended address bits from supersection short descriptor Since ARMv7 with LPAE support, a supersection short translation table descriptor has had extended base address fields which hold bits 39:32 of translated address. These fields are IMPDEF in ARMv6 and ARMv7 without LPAE support.
