U-Boot is just a bootloader, like Grub, the only useful thing it does,
is booting embedded Linux. Not sure why you'd want to tinker with that,
because if you misconfigure/damage it, you may find your hardware no
longer boots.
Actually, it does a fair bit more than "just boot Linux" -- hence the
reason to tinker with it! :> (why would it have a command interpreter if
the only thing it could do was "boot"?)
[Hint: ask yourself what you'd do if you didn't have the password to the ILOM;
or, if the Linux image had been corrupted/wouldn't boot; or if you wanted to
reflash that image (e.g., to support 11.4); or, if the serial port wasn't
"connected" to the ILOM]
For folks like me who acquire these devices without being able to
speak to the previous owner ("what's root's password?"), it's an
essential tool to getting into a box that may typically have been
locked up to prevent casual access (esp as you can't "pull the SP's
disk" to alter its contents off-line)
The hooks have been placed there, for a reason. Silly NOT to understand
them and use them!
But anyway, good luck with your investigations

I have Sun Enterprise T5220 and here are some of my opinions: 1. Currently NetBSD does not have good support for this CPU architecture, so it probably won't run. I think OpenBSD supports it much better and also has support for LDOMs. So if you want BSD then OpenBSD is the only option (I think FreeBSD dropped sun4v a long time ago due to lack of interest/resources?). 2.

However if you're not using hardware in a production environment, then you may not need all the latest features and bug fixes.
Re: Netra T5220
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.

You will be stuck on Solaris 11.3 if you take that path... just saying :) -- Brett Lymn Let go, or be dragged - Zen proverb.
