From bc2df1afb92435da6fb16310dac6b722bfaade9f Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 28 Feb 2013 19:26:12 +0000 Subject: x86: Permit bootstage and timer data to be used prior to relocation It is useful to be able to access the timer before U-Boot has relocated so that we can fully support bootstage. Add new global_data members to support this.
