Building Rom - project carbon

Hi I'm interested in building ROMs for our tf300. I've tried building ROMs before both on my desire HD and this last weekend for the tf300t, but I've always run into problems: especially when I wanna build a ROM for a device that isn't officially supported.
For instance, I would like to unofficially build carbon ROM for the tf300t.
I know how to setup the computer in Linux and its all setup. I know how to repo init. I know how to repo sync.
Now for the hard part. Correct me if I'm wrong. In order to build an unofficial ROM I would need to pull the device tree and vendor tree, right, and put them into the repo that I repo synced earlier? Then I would need to update the local manifest to include those device and vendor trees?
I have several questions about it.
First, where can I get the device and vendor trees? It seems as if drgravy has some good trees, maybe I can use those?
Second, would those device and vendor trees have the 4.2 BL support or is that a different change?
Third, would I need to change the repo to build a proper kernel for the tf300t or would the device tree or vendor tree include the kernel source? Any help would be awesome.
Also in replying to this please don't just post a link. I've read a lot about the process, I just had some specific questions.
Thanks

[Q] Help Building unofficial ROM

I'm trying to build unofficial Dirty Unicorns for the TF300T. I've been using this tutorial to set up my build environment:
http://forum.xda-developers.com/chef-central/android/tutorial-compile-lollipop-ubuntu-t2929410
I've managed to sync their repos and all that, and I've come to the device tree. I wasn't able to find an equivalent tree on Google's website like the Nexus 7. So my question is, where can I find the tree(s) for my Transformer? Is building for a device really as simple as combining the repo, device trees, and blobs? That's what this tutorial implies. Or am I likely to end up with a crappy build?

Wow.

you might be able to find the device tree from the omni rom guys. Last time I tried to do this it was for my ME301. I was able to download the device tree from the Omonirom gerrit page. Poke around the Omnirom guys site and thread and see if they have it. Here ya go. This is the cyanogen github page. it looks like they list both the tf300t kernel and the device tree for cyanogen mod ROM
https://github.com/CyanogenMod?utf8=✓&query=tf300t
That might be a start
Here is the wiki page for building Cyanogen Mod for the tf300t and it might explain some steps better

Questions about building a custom ROM from AOSP

Hi, I am currently building custom rom for my Lenovo a7000-a (aio_row) and I have a few questions regarding the device section of the AOSP build.
1. I have seen that to build the custom ROM for a device, I would need the following .mk files from topic "Android device configuration AOSP" in Stackoverflow.
However, from the device configuration/device-tree(?) from user rohantaneja in Github, I see that I would also need files that look like drivers for the devices based on the files on that github. May I ask how would I obtain these files?
2. Would flashing an arm64 generic build of custom AOSP into any Android device work or not? If so, why?
Seems like the amount of knowledge that I faced off with confused me a lot.
Any help is appreciated.
Thanks in advanced.

General [info] Xiaomi 13 (fuxi) Open Source Kernel and Lineage Device Tree

Hi all,
For those of you, like me, who are interested in learning more about developing for custom ROMs, the following links will be helpful for finding .
First is the inclusive list of open source kernel releases by Xiaomi: https://github.com/MiCode/Xiaomi_Kernel_OpenSource
At the bottom of said list is the Xiaomi 13 (fuxi).
Second is the device tree (based on Lineage OS and said to be WIP) by YuKongA: https://github.com/YuKongA/device_xiaomi_fuxi

What is the primary difference between official xiaomi 13's device tree https://github.com/MiCode/kernel_devicetree/tree/fuxi-t-oss and https://github.com/YuKongA/device_xiaomi_fuxi ?

YuKongA's contribution is for Lineage OS, or instead of MIUI it's AOSP. I think.

To give additional information, the Lineage-derived device tree likely originates from: https://github.com/imasaru/android_device_tree_template

Also, the kernel includes a lot of stuff for the hardware and is accompanied by a kernel device tree, which is a kind of 'table of contents' (unless I'm mistaken about the analogy).
"The 'Open Firmware Device Tree', or simply Devicetree (DT), is a data structure and language for describing hardware."
Linux and the Devicetree — The Linux Kernel documentation
I imagine a lot of compatibility issues are lining up the system image and the kernel+device tree.
...
(At this point, I'm really just spouting off some things as I'm learning, so feel free to correct or ignore me as I'm going along!)
