Progress

I'm busying with my daily work, so i have limit time to do this.

There are many developers working on Android 10/11/12 on this device. If there's no possible to work on further, I will try to call them working on it.

I aim to base on 6.1.46 and continue working.

This device comes with a interesting boot package method, which dt.img isn't QCDT style at all. Instead, it just use dtb file as dt.img.
