[Gta04-owner] Replicant images on GTA04 release

Hallo Paul,
another feedback from Replicant on my gta04:
Installation with skripts works smooth, although on bootloader-flashing
my LED gives me "orange" for approx. 1 sec, then turns "green" for a
second then turns black ...

The system itself runs stable and with impressing speed! Great job ! :-)

As you already mentioned, wakeup/resume doesn't work (only cursor on
black screen). Calls seem to work (I heard my other phone ring). I
didn't test USB but will give it a try tomorrow.

Can you give us a more detailed Replicant help page to start with? I
couldn't find more in-depth documentation on replicant.us.

Keep on the great work!

Finally, the first batch of Replicant images for GTA04 is out!

I know it has been a while since I promised images and apologize for
being so late. 

So let's start with what works and is implemented in this release:
* Android kernel based on Neil's 3.2 branch
* Audio input/output/mixer, sound during calls on A4 only
* Graphics, that are really fast and usable
* Backlight, leds, battery
* Modem has working calls

Now what does not work (but will probably be improved over the next
* Headset detection and associated scenarios
* Suspend/resume fails very often
* Audio routing during calls isn't implemented for A3
* Modem has very limited support since I didn't implement all the AT
commands yet
* WiFi, bluetooth, GPS, vibrator and sensors are missing

Here are some notes:
* Sometimes, the modem does USB disconnect and I can't bring it back
using the GPIO node
* Modem is turned on during board bootup (with explicit gpio setting)
but when the phones turns off, the Modem seems still on and keeps
draining power.
* Replicant runs on uSD only since NAND is apparently unreliable with
3.x kernels
* We will switch GTA04 to Android 4.0 in the future if it can be as fast

The images can be downloaded from:
Just download all the files listed on the GTA04 line.
