Yes great thanks.

I had a quick look at the email history before posting, but now I see I was only looking at the 0/2 patch :)
I see I replied to you but as you say the pastebin is gone. From what I wrote it looks like it was a GDP build-dep
warning. If you have the warnings still around send them on and I will keep an eye out.

I have not finally decided yet. The eval licensing for Koelsch and the other "Pro" Evaluation boards means
there is some advantages to sticking with gfx acceleration only by default, as you have the option of using
the gfx from the low cost board click-through licensing. It is not so clear cut for the multimedia.
So as GDP doesn't yet make much use of multimedia acceleration I may keep it off for the Eval boards by default
until projects like GAAP make it more of a necessity. If a dev has the multimedia for the Evaluation boards then its straight
forward to enable anyway. That said the reverse is also true :)
For the M2 Porter and E2 Silk Low Cost boards, then yes definitely gfx and multimedia enabled by default.

Yes I'll create a branch. What have you found worked best when doing a variant if something
close to it is already available? Branch from the existing branch, make the needed changes and push
the new branch, or start blank and add the submodules in? Obviously either is possible I just
wonder if you found submodules have some peculiarity that favours one over the other?
The only source change for GDP on Silk is a couple of lines to generalise the image package list
that currently references the Porter and Koelsch MACHINE to be for all R-Car Gen 2 boards.
That's a patch to meta-genivi-demo I will send first, but yes the same commit can be used by all.
Completely agree with the maintenance point.
It will be nice when we start tracking the HEADs. It can seem a bit of an anti-pattern sometimes
updating the git submodules step by step. Although that may in part be me getting more used to it.
