From 16fe79048f5254661ff2342aa481cbb44657b7ff Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Wed, 12 Apr 2017 17:01:31 +0200 Subject: sb/intel/*: Use common SMBus functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All Intel southbridges implement the same SMBus functions. This patch replaces all these similar and mostly identical implementations with a common file. This also makes i2c block read available to all those southbridges. If the northbridge has to read a lot of SPD bytes sequentially, using this function can reduce the time being spent to read SPD five-fold.
