From 50a6fe73c6304077a959c483d0d31054ce7177b2 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sat, 14 Nov 2020 01:18:14 +0100 Subject: nb/intel/sandybridge: Remove unnecessary per-rank loops The IOSAV_By_BW_MASK_ch registers are not per-rank. To preserve original behavior, use a for-populated-channels loop instead of for-all-channels. Tested on Asus P8H61-M PRO, still boots.
