From b60eff31f3bd71a6f14b6c6efc8ad5fb3705de6d Mon Sep 17 00:00:00 2001 From: Albert ARIBAUD Date: Sat, 22 Feb 2014 17:53:43 +0100 Subject: arm: remove unneeded symbol offsets and _TEXT_BASE Remove the last uses of symbol offsets in ARM U-Boot. Remove some needless uses of _TEXT_BASE. Remove all _TEXT_BASE definitions.
