Combining defconfigs for 44x based boards

Combining defconfigs for 44x based boards

[Tirumala Marri]

Is anyone working on Linus suggestion to combine the defconfigs under 44x
or 4xx ?
Thanks,
Marri

Linus made a suggestion to that effect?  If so, I missed it.  Have a
pointer?

There was discussion going on in arm-kernel mailing list. And I see some
patches being submitted for ARM based boards.
I think we can also combine some of the defconfigs under
arch/powerpc/configs/44x/ directory.

Here is ARM dfconfigs discussion
http://lkml.indiana.edu/hypermail/linux/kernel/1006.0/01464.html

Here is the link for some of the defconfig submissions

I am thinking that we can combine arches, Canyonlands, glacier, redwood
and eiger can be combined as ppc46x_defconfig.

We already have arch/powerpc/configs/ppc40x_defconfig and
arch/powerpc/configs/ppc44x_defconfig in mainline.

What's wrong with using these?

[Marri] Great we already have it. We should remove the defconfigs under
44x then ?

I'd rather we didn't. I thought Linus' beef was over the churn in the
defconfigs, not the fact that they exist. The 44x defconfigs change
very rarely.

[Marri]That is kind of true. Can we create new defconfigs then ?
I am trying to check-in new defconfig.

Just make sure that it is minimal by using "make savedefconfig".  This
will create a file "defconfig" in the current directory which should have
the minimal amount of stuff in it to reproduce the current .config.

Do you mean ppc44x_defconfig? Already there.

No it is not there yet. I should have said "Linus suggestion about
defconfigs in ARM mailing list".

ARM and powerpc are somewhat different in this aspect, since
ARM traditionally has not been able to build multiplatform kernels
(especially not multi-soc-family kernels).

Powerpc can build a kernel that will boot on all machines of a certain
class (server, fsl-booke, ibm-booke, ppc32). So there's not really
a whole lot of reason to have the custom per-board defconfigs in the
kernel tree any more.

For specific products it might still make sense for a vendor to make a custom
minimal defconfig, but that doesn't mean it's a requirement to have them in the
upstream repository.

Are arch/powerpc/configs/ppc44x_defconfig and ppc40x_defconfig what you want?
Or do you mean the Kconfig based versions?
