From 10d602ac8b6f576d545e35a951e1a714de0158a3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 31 May 2017 17:57:13 -0600 Subject: arm: Don't try to support CONFIG_ARMV7_LPAE on ARMv4T At present if CONFIG_ARMV7_LPAE is defined then mmu_setup() will use instructions which are invalid on ARMv4T. This happens on Tegra since it has an ARMv4T boot CPU. Add a check for the architecture version to allow the code to be built. It will not actually be executed by the boot CPU, but needs to compile.
