From 2f66a828f7621958b6925fc763380fa87be55ee6 Mon Sep 17 00:00:00 2001 From: Ying Zhang Date: Fri, 22 Jan 2016 12:15:13 +0800 Subject: powerpc/board/t4240rdb: Enable VID support The fuse status register provides the values from on-chip voltage ID efuses programmed at the factory. These values define the voltage requirements for the chip. u-boot reads FUSESR and translates the values into the appropriate commands to set the voltage output value of an external voltage regulator.
