From 44e5e4ce73153ae17442daae11e89b40815a4c90 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 5 Aug 2014 13:30:38 -0500 Subject: tegra132: use pre-existing reset API coreboot already has a reset API. Utilize it by selecting HAVE_HARD_RESET. The tegra132 boards have to provide the hard_reset() implementation as that involves board-specific bits. The tegra132 code then provides a cpu_reset() routine that just promotes that call to a hard_reset(). For the existing tegra132 boards remove the unnecessary files from the build. BUG=chrome-os-partner:30784 BRANCH=None TEST=Ensured hard_reset() does something on Ryu.
