Hi,
For reference, here is (I believe) the current list of Tegra patches
required become submitting new patches. I note a few conflicts
already, so this will take a little sorting out once the tegra tree is
live.

I assume that means we can assume these are all accepted and will be
merged, so we should apply them locally and build on top of them?
Is there a status update for the creation of a Tegra git that we could
fetch and branch from ?
Note that already, I think some of the later patches need rework given
earlier ones, e.g. there was some change to board/nvidia/common/Makefile
that required other boards using it to be updated, but the Ventana
Makefile wasn't IIRC. I guess that's what you meant by conflicts.
Thanks for the list!

Well I could put up a tree, but it's a bit dangerous - the real place
is patchwork.

Yes that's right. Hopefully the pain will reduce soon!

You are welcome.

I thought there was going to be a u-boot-tegra.git that a Tegra U-boot
maintainer would put the patches into once reviewed/approved, and then
send pull requests to Albert, like the other ARM SoCs? That's what I was
expecting to rebase on top of. Sure some patches will still be waiting
in patchwork, but the volume would presumably be a lot lower, and
there'd be fewer conflicts.

Yes and I think Tom volunteered to run that! Once it is up and going
we should be able to find everything we need there.
But until then we need to rely on patchwork and keeping our own tree
locally. My copy of these patches is at
http://git.denx.de/u-boot-simonglass.git (branch us-tegra) but it
includes all my 'patman' junk, and resolution of some patch conflicts,
etc. So really only useful for comparing. I am using it to base
further patches on, of which there are many as you know.
BTW my SPI series didn't really get a lot of comments - are you happy
with the UART switch stuff? It is an incomplete implementation since
the NS16550 buffering patch was NAKed. Mike suggested another option
we could do to get around calling pinmux code in NS16650 and Tegra
SPI, but in any case it might be dead in the water without serial
buffering. I have put it down as something to look at 'later'.

Yes, there will be. I just didn't get to that yet.

Sorry.
