So far I've got the basic A51x/A70x support added to my linux-tegra-nv-3.4 branch.

What works:
- The kernel boots
- Panel (partially?)
- USB
- Android is trying to start

Whatnot:
- everything else

So my first goal is to get display up. Currently, I've got a black screen after the bootloader logo, and the following logs:
dmesg
logcat

If anyone can help with this, hit me on hangouts, my g+ profile can be found on my xda profile. I'd appreciate any help, this would be a huge step forward for these devices.

Great work so far !
I quickly looked at your logs, there is some problem with the GPU and SurfaceFlinger can't start.
I'm not very good with Kernel specific devs, but at this point maybe you will have to upgrade hardware libs (egl, etc.).

Maybe you can try to use some Nexus 7 2012 vendor blobs : https://developers.google.com/androi...#grouperktu84p

Newer ones may be needed for 3.4, dunno... also, I may have just missed something simple...
Code:
W/SurfaceFlinger(  266): no suitable EGLConfig found, trying a simpler query
F/SurfaceFlinger(  266): no suitable EGLConfig found, giving up
...
D/NvOsDebugPrintf(  270): NvRmPrivGetChipIdStub: Could not read Tegra chip id/rev
D/NvOsDebugPrintf(  270): Expected on kernels without Tegra3 support, using Tegra2
Anyways, I'm still working on 3.1, refactoring Acer's mess with the kernel files outside the kernel files... minimizing those changes will ease 3.4 development a lot, as it's confusing to watch out for Acer ifdef's all around the kernel

I don't have the device ATM, so I can't do anything related to this.
