OK, I've updated it according to your comments and ensured it still
works on my GPSP.

I have based the patch on the ARM tree because it includes some dtsi
files that are needed by this patch. Please find it attached.

Best regards,
Willy

Subject: ARM: kirkwood: convert Guruplug Server Plus to device tree

Add a device tree entry for the Guruplug Server Plus board. This port
was based both on the work done on the dreamplug and the dockstar.

It builds, boots and works on my Guruplug Server Plus.

One small typo, should be "...server-plus".  If there are no other
comments over the next few days, I'll tweak it when I pull it in.

thx,

I'm amazed, because you did exactly the same one in your initial review
last week and I noticed it back then. Then I did this one without copy-
pasting yours! It seems like our brain is too much attracted by those
similarly looking letters. Sorry for this one.

Thanks,
Willy

It's probably more of a pattern-completion mechanism in the brain.  We
type/think p-l-u-g more often than p-l-u-s.  So, when you are on
auto-pilot doing a simple change, the brain prefers 'g' over 's' to
complete p-l-u... Or, we're both just dumb. ;-)

I'm pretty sure there's a PhD candidate neurobiologist lurking on the
list who just found their thesis topic...

thx,

Jason.

I'm assuming you meant kirkwood instead of mvebu here, but thanks anyway !

mach-mvebu is where everything is being migrated to once the DT
conversion is complete.  We use the name internally to refer to any SoCs
created by Marvell in the EBU division.

So, yes, it's kirkwood, but it falls under mvebu stuff.  Just like dove
and orion5x.

hth,

Jason.

OK, that was not obvious to me, since till now for me mvebu was only
the new armada370/XP boards. But that makes sense and it will certainly
make code sharing easier !

Thanks for your explanation!
