Hopefully I have taken the complete one from the original ... :/
This complete git repo can be found here.
http://git.coolstreamtech.de/?p=cst-public-linux-kernel.git;a=shortlog;h=refs/heads/2.6.34.13-cnxt

The related kernel patches I placed under
board/coolstream/hdx/kernel-2.6.34-patches
The config right in board/coolstream/hdx/kernel2.6.34.13.config

The platform is a ARMv6 based Settopbox with a SoC from Nexperia
(cx2450). There are closed kernel modules that have to be used, so most
parts of the kernel config depended on this, but some options are
configurable without to recompile this closed source parts.

I configured BR to build a GCC 4.7.1 with crosstool-ng, after some fine
tuning this works.

My BR config looks like this.

The kernel config is appended.

If something is missing then just let me know.

Thanks in advice!
