Unfortunately, as of 5 Nov 2017 ( http://mail-index.netbsd.org/port-sparc64/2017/11/05/msg002700.html ) and according to the official netbsd wiki page ( http://wiki.netbsd.org/ports/sparc64/ ), netbsd does not support sun4v architecture yet... it does seems however somebody at netbsd is trying to make it work ( http://www.netbsd.org/~palle/sun4v/ ).
IMHO, you should stick to solaris 10 or 11 if you want to get the maximum from the hardware ( LDOMs and possibility to write to eeprom from OS ). If you want an alternative, Oracle has ported RHEL6 to sun4v. You can download it here : https://www.oracle.com/technetwork/server-storage/linux/downloads/oracle-linux-sparc-3665558.html Nevertheless, RHEL6 is kinda old ( Released on 2010 alongside NetBSD 5.1 ). Red Hat should EOL it on 2020. Oracle should EOL OEL6 (x86_64?) in 2021. Else, if you really want to help NetBSD project you should contact the sparc64 port admin. Choice is yours.
