From 50c0a50ac6a3fa54ed1286e8b76f933701b6d053 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Thu, 31 Jan 2013 17:05:50 -0800 Subject: armv7: unify stage hand-off routines This replaces the current stage-specific exit/entry functions with generic versions. Now all stages compile with stage_entry(), which is placed at .text.stage_entry.armv7, and stage_exit(). Snow's ramstage files are also updated to avoid build breakage.
