From ce90c78d7f27e41275deb36b5dea2787ffced8bf Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Wed, 30 Aug 2017 16:53:20 +0530 Subject: soc/intel/apollolake: Use SMM library to get tseg region information This patch uses smm common library function to get tseg base address and size. Hence removing definitions of smm_region() from soc directory. BRANCH=none BUG=b:63974384 TEST=Build and boot reef successfully.
