No upstream change summary, but the old version no longer worked with
modern coreboot.
Distfile created from a full clone of the coreboot tree with below script;
#!/bin/sh
cbver=`git describe`
cbobj=`git ls-tree origin/master util/nvramtool|awk '{print $3}'|cut -c 1-7`
distname=nvramtool-"$cbver"-"$cbobj"
git archive -o /tmp/"$distname".tar.gz --prefix="$distname"/ "$cbobj"
nvramtool is a utility for reading/writing coreboot parameters and
displaying information from the coreboot table in CMOS.
The program works only on x86-based systems that use coreboot.
