From e9a2f8b599d0bc22a1b13e69527246ac39c697b4 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Sun, 11 Oct 2020 10:20:16 +0100 Subject: ARM: 9011/1: centralize phys-to-virt conversion of DT/ATAGS address Before moving the DT mapping out of the linear region, let's prepare for this change by removing all the phys-to-virt translations of the __atags_pointer variable, and perform this translation only once at setup time.
