Where's BOARD_AVB_ENABLE? (Verified Boot Android)

[natmendes]

So, I've downloaded the source code of Android Oreo 8.0. I want to enable the Verified Boot using this flag, and also putting different flags (like BOARD_AVB_ALGORITHM) to configure this. But I can't find which file this configurations are.

Anyone know this? Thanks!
