I'm wondering if there're any comments on this one.
Otherwise please consider applying.

This patch is a prerequisite for ARC port submission I'm going to send out
shortly.

This is a quick jump to invalid conclusions, the changes that Alexey is
submitting are to files under scripts/* which are only used during the
build process in this case, and there are no GPLv3 components being
included in the firmware image per-se.

These specific files are used by autotools and friends to detect the
architecture/machine we cross-compile for, and as such as a prerequisite
for supporting an ARC toolchain.

As such, the changes are completely fine, and have no bearing to the
resulting firmware image.

Although I do share the same feeling, I think the justification is way
off, GPLv3 does not prevent anybody from contributing, it may just hurt
your distribution model, which is something entirely different.

Alexey,

Is there a particular reason that this architecture must be submitted
to OpenWrt under the terms GPL v3+? I would prefer that OpenWrt stick
to GPL v2 in order to maintain better compatibility with the Linux
kernel (kernel.org). The kernel is primarily GPL v2 licensed (or
something FreeBSD-like which is more, not less, permissive). The
OpenWrt distro has only a few GPL v3 package exceptions, such as
samba.

The OpenWrt core team are doing a good job building a better
industry-community relationship for OpenWrt, which I think can be a
win-win for overall project improvement (brings in more developer
resources, much like kernel development depends on industry
developers). Introducing more GPL v3 packages makes it problematic for
certain industry partners to be able to fully collaborate.

[OpenWrt-Devel] [PATCH] update config.guess config.sub

2015-07-30 Thread Alexey Brodkin 
These are from today's master branch of:
http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree

In particular it adds support for ARC architecture plus some more
improvements and fixes.

This patch is built-tested against NetGear WNDR3800.
