From b0b403d954081520ba82fef24dee6486ffebe017 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 31 Jul 2015 09:31:27 -0600 Subject: [PATCH] Reserve the top 16 flag bits for architecture-specific use Add a convention that the generic global_data only occupy the bottom 16 bits of the flags word, so that there is less chance of a conflict. At present the x86 flags conflict.
