Thanks a lot! Support for such platforms is very welcome!

I have a couple of comments below, though.

Your patch is wrapped, something is wrong in your e-mail configuration.

Moreover, the Buildroot configuration file should be a minimal
configuration. To do so :

	make savedefconfig
	cp defconfig configs/soekris-net4501_defconfig

Why do you need a special Busybox configuration file ?

Could you detail the differences with the default device table ?

It should be stored in:

	board/soekris/net4501

And it should be a minimal kernel configuration. So in your kernel tree:

	make savedefconfig

and then

	cp defconfig /path/to/buildroot/board/soekris/net4501/linux-x.y.z.config

Could you highlight the differences between this target skeleton and
the default one ? I'm trying to avoid the duplication of skeletons, so
I need to understand what this one adds, and how we can solve it
without duplicating the complete target skeleton.

Could you detail why a specific uClibc configuration is needed compared
to the default one we ship in toolchain/uClibc/ ?

Thanks a lot!
