grub2/util/grub-install.c
Colin Watson 65b75fc8dc Port yaboot logic for various powerpc machine types 
Some powerpc machines require not updating the NVRAM.  This can be handled
by existing grub-install command-line options, but it's friendlier to detect
this automatically.

On chrp_ibm machines, use the nvram utility rather than nvsetenv.  (This
is possibly suitable for other machines too, but that needs to be
verified.)
