Here's my adam device tree for android 4.0.1 ASOP.
Copy to android/device/notionink/adam/
run extract-files.sh or copy-files.sh that'll create your vendor directory
go back to source root
Shell Type: ". build/envsetup.sh"
Let it finish.
Shell Type: "lunch full_adam-userdebug"
Wait for it to get done.
Then type: "time make -j16" (replace 16 with whatever your machine can handle.)
