From 244cf7d3a6d8db2a2ea5541815a0bd4e564c8195 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sat, 5 Dec 2020 20:25:27 +0100 Subject: sb/intel/x/smbus.c: Add block read/write support Copy and paste the i82801gx code onto all newer southbridges. This will be factored out into common code in a follow-up.
