From e05e5de7fae5bec79617e113916dac6631251156 Mon Sep 17 00:00:00 2001 From: Albert ARIBAUD Date: Tue, 8 Jan 2013 10:18:02 +0000 Subject: arm: move C runtime setup code in crt0.S Move all the C runtime setup code from every start.S in arch/arm into arch/arm/lib/crt0.S. This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed.
