[Q] Informations for building a new Device tree for a unsupported Device

Hi Everybody,

I want to ask for some informations what is need to do to build SlimRom for a new device. I found a lot of informations about CM, but nothing is really in a way that I really know what I have to do at the end. So is there a Howto, which describes it a little bit more in detail? A lot of howtos was found which describe to get a build-system, and to generate something for a know device. But everybody then describes only: you have to get the vendor files, made your Board-config but only on a very high level.
What I did:
- set up a building-server on ubuntu.
- get Slim-Sources branch JB4.3, and build the version for galaxysmtd to be sure that the buildprocess is ok.
- get "Nonreallyfree"-Opensources from Samsung for my I8200, and try to put them in the right places, and try to implement all needed files in the device/samsung/i8200 folder.

Up to now I think I have everything in place more or less, but the system told me that there is no rule for make 'bacon', but lunch seems to work right with setting the variables...

Up to now I did not used the blobs of the devices. The question is, if that is needed if I have the sources from open Samsung?

I know, jb43 is not the newest, but I start here, because up to now the sources are based on that level, and the kernel have no selinux implemented... If this start point will work, then I will try to go ahead with higher versions... end goal will be Slimkat...

Any help is very much appreciated!!
