From f05ad9ba4c22b5c5929406394a0889791c2778da Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 4 Aug 2015 12:33:39 -0600 Subject: Add a way to skip relocation When running U-Boot as an EFI application we cannot relocate since we do not have relocation information. U-Boot has already been relocated to a suitable address. Add a global_data flag to control skipping relocation.
