From 7124015adad59dea5e72103f63531f3367c6df80 Mon Sep 17 00:00:00 2001 From: Ben Gardiner <bengardiner@nanometrics.ca> Date: Thu, 28 Apr 2011 11:03:21 +0000 Subject: [PATCH] README.arm-relocation: get relocated address in gdb When your emulator is connected at reset (or is used to load u-boot) it is possible to get the relocation address from the gd->relocaddr since gd is always in r8 (on ARM) it is addressable before the gdb has remapped symbols. Document this alternate method in-line with the original method written by Heiko Schocher.
