The partial version of faraday cpu datasheet with only
the CP15 and MPU description are available at my Google Drive:

The pre-built A369 images are also available at my Google Drive:

https://docs.google.com/folder/d/0BwfiewvSmUgAX2pTTmtUMGFCZW8/edit

Here is the image file list:

1. android-4.0.4/zImage: A369 linux-3.0.31
2. android-4.0.4/romfs-4.0.4.tar.bz2: android-4.0.4
3. nand.img.bz2: A369 nand flash image

If you want to re-build the image from scratch, 
try my Faraday Linux BSP/SDK: falinux.

1. Download the falinux

   $ git clone https://github.com/dantesu1218/falinux.git

2. Download all the required software packages:

   $ cd falinux
   $ make setup

3. Launch the menuconfig of falinux, and enable 'QEMU Support'

   $ make menuconfig

4. Re-build the packages

   $ make

5. Laungh the qemu-1.3.0 with the generated falinux images.

   $ make qemu
