commit 619af0afe29e3801501b2bca69bee27f12939cd7 Author: Gabe Black gabeblack@google.com Date: Sun Sep 29 05:40:13 2013 -0700
ARM: Make it possible to use a custom bootblock implementation.
Tegra needs to use a custom bootblock implementation because it starts on a coprocessor which uses ARMv4. It doesn't have the same control registers, caches, etc., and the regular bootblock gets exceptions and dies.
