From f677d17ab3cfd1471c0f238a0d32b0d56dd8d37f Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Mon, 1 Oct 2018 19:17:11 +0200 Subject: intel: Use CF9 reset (part 2) Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also implement board_reset() as a "full reset" (aka. cold reset) as that is what was used here for hard_reset(). Drop soc_reset_prepare() thereby, as it was only used for APL. Also, move the global-reset logic. We leave some comments to remind us that a system_reset() should be enough, where a full_reset() is called now (to retain current behaviour) and looks suspicious. Note, as no global_reset() is implemented for Denverton-NS, we halt there now instead of issuing a non-global reset. This seems safer; a non-global reset might result in a reset loop.
