Re: Reminder: removal of arch/ppc - (Sequoia)

The Sequoia board (AMCC-440EPx processor) is missing from the new 
arch/powerpc. The Sequoia board is also missing from arch/ppc , but 
there is support for integrated devices on the AMCC part inside 
arch/ppc that needs to be incorporated into arch/powerpc. In 
addition, there needs to be a "sequoia.c" file added to the 
arch/powerpc/44x directory.  I have a good start on the missing 
pieces and a test platform, is this contribution desired?

Hello!

Yes! I'm looking at 2.6.23.14 as I thought that was the newest 
version. I completely missed seeing the 2.6.24 kit, thank you so much!!

2.6.24 already has sequoia support in arch/powerpc. Are you looking at
an older tree?

FYI, 2.6.24 is considered fairly old relatively speaking.  With so much
activity going on for the embedded boards for arch/powerpc, you're sort
of missing out if you aren't running from the latest git trees.

Yes, I realize how ridiculous it sounds to say a kernel that was just
released 3 days ago is old, but that's reality.

Hey Josh, thank you so much for the pointer to the git trees. I've 
been using Linus' kernel.org tree, as that's where I was pointed to 
by the powerpc web site about 2 months ago. I sure do appreciate your 
updated pointer to the git tree, I will now locate it and stay tuned 
and participate.

What's the best/preferred GIT URL for current, up-to-date arch/powerpc
activity? Is it?

    git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc

I am particularly interested in Kilauea/Haleakala-related development.

Regards,

Grant Erickson

Yep, that's the canonical source.

My tree:

git://git.kernel.org/pub/scm/linux/kernel/git/jwboyer/powerpc-4xx.git 

might briefly have some stuff for those that Paul's doesn't at times,
but as of right now they are synced up.  Typically there are only
changes on the next kernel branch during the development period for
that particular version.

Preferred GIT URL for arch/powerpc, and BINUTILS

[Steve Heflin]

Josh, you're a life saver!!  Your GIT tree is exactly what I've been 
looking for. I have an AMCC440EPx based product that makes heavy use 
of all the devices embedded in the microcontroller. I'll be able to 
give that platform a very good testing.

Now can you help me with BINUTILS?  What version do you use and can 
you point me to a decent GIT tree for it?  I tried to use version 
2.18 and the build blows up because it tries to "strip" a script file 
"embedspu".

thanks so much,
Steve

Whoa! I spoke too soon.  Upon attempting a "make menuconfig" on the 
2.6.24-rc8 which I cloned from your git tree, I don't even SEE the 
powerpc architecture appearing!  What's up?

I dunno.  I never use make menuconfig.  I typically do:

make ARCH=powerpc sequoia_defconfig

or something similar if I'm cross-building from x86.  Otherwise if I'm
on the G5, it's just:

make sequoia_defconfig

Oh, and that's on the for-2.6.25 branch of my tree.  I'll update the
master soon-ish to match the powerpc git tree.
