From ab86f72c354f9b2572340f72b74ca0a258c451bd Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Fri, 17 Sep 2010 13:10:42 +0200 Subject: ARM: implement relocation for ARM926 Change the implementation for arm926 to relocate the code to an arbitrary address in RAM. Adapt the TX25 (i.MX25), magnesium board to test the changes. On the tx25 board TEXT_BASE is set to the final relocation address to prevent one more copying of u-boot code when relocating.
