From fb970a43bd69e36e4fc8a98883d0525f6b071eb5 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Thu, 24 Nov 2022 19:42:55 +0530 Subject: soc/intel/meteorlake: Refactor heci finalize functions This patch creates a helper function `heci_finalize()` to keep HECI related operations separated for easy guarding again FSP config. Currently, `heci_set_to_d0i3()` function is getting called twice.
