From a737028e80603f49a4757adec10b5842d0689dbb Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Thu, 14 Jan 2016 14:03:11 -0700 Subject: arm: initialize gd for AArch64 Commit adc421e4cee8 "arm: move gd handling outside of C code" removed the call to arch_setup_gd() on ARM and replaced it with assembly code in crt0.S. However, AArch64 uses a different startup file, and the same change was not made to it. This leaves gd uninitialized on AArch64, which typically leads to hangs or crashes. This change fixes that.
