From e5abb92c0b5dd8bd37b0b7a0881e60d82616099f Mon Sep 17 00:00:00 2001 From: Ying Zhang Date: Tue, 10 Mar 2015 14:21:36 +0800 Subject: board/t208xrdb: 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.
