How to build:

1. Establish Android build environment and install repo.

2. Initialize repo:

$ repo init -u https://android.googlesource.com/kernel/manifest -b common-android14-6.1-lts
$ curl -o .repo/local_manifests/manifest_brcm_rpi.xml -L https://raw.githubusercontent.com/clear-code/android_kernel_brcm_rpi_manifest/android-14.0-docker/manifest_brcm_rpi.xml --create-dirs

3. Sync source code:

$ repo sync

4. Compile:

Raspberry Pi 5:

$ tools/bazel build --config=fast --config=stamp //common:rpi5docker

Compiled kernel Image, dtbs, and overlays can be found in bazel-bin/common/rpi5docker/arch/arm64/boot directory.

Replace existing files in device/brcm/rpi5-kernel directory of the Android source tree to include them in Android 14 build. You can also replace existing files in the boot partition of Raspberry Pi 5 Android 14 image.
