[Qemu-devel] [PATCH 1/5] target-arm: there is no TTBR1 for 32-bit EL2 st


From: Peter Maydell
Subject: [Qemu-devel] [PATCH 1/5] target-arm: there is no TTBR1 for 32-bit EL2 stage 1 translations
Date: Fri, 24 Jul 2015 16:20:59 +0100

For EL2 stage 1 translations, there is no TTBR1. We were already
handling this for 64-bit EL2; add the code to take the 'no TTBR1'
code path for 64-bit EL2 as well.
