From: Joakim Tjernlund Date: Fri, 28 Mar 2008 14:41:25 +0000 (+0100) Subject: Make MPC83xx one step closer to full relocation. X-Git-Tag: v1.3.3-rc1~117^2 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=70431e8a;p=oweals%2Fu-boot.git Make MPC83xx one step closer to full relocation. Remove a few absolute references to CFG_MONITOR_BASE for ppc/mpc83xx and use GOT relative reference.
