How to build Android u-boot?

For many people it is a mystery how to build Android u-boot on the local machine.

The one which is developed here:

Now you'll have a working answer:

Create a fork of this repository
Go to https://ci.android.com/builds/branches/aosp_u-boot-mainline/grid?
Select the u-boot build, which you would like to build locally. Open it's artifacts.
Inside the artifacts open the manifest_xyz.xml artifact, where xyz would be the opened CI/CD job number ( e.g. 9670045 )
Copy paste content of the file into the default.xml
Commit the changes

Call ./build.sh inside the cloned repository folder in the following way:

./build.sh <BUILD_DIR> <MANIFEST_URL> <MANIFEST_BRANCH> <U_BOOT_BUILD_CONFIG>

Parameter	Meaning
BUILD_DIR	Target build directory.
MANIFEST_GIT_URL	URL of your fork of this repo.
MANIFEST_GIT_BRANCH	The branch within the MANIFEST_GIT_URL, which you would like to use.
U_BOOT_BUILD_TARGET	The <target>_<arch> literal, e.g. qemu_aarch64 or crosvm_x86_64

All parameters are mandatory. No default values applied.

The build.sh script will trigger "repo init" + "repo sync" + "bazel build"

As a quickstart, here is an example of calling a script, which should work even without a fork, right after cloning this repo:

./build.sh /mnt/manual_android_uboot_build https://github.com/svlad-90/android-u-boot-build.git master qemu_aarch64

The resulting artifacts will bе located in the following directory:
```
${BUILD_DIR}/out/dist/${U_BOOT_BUILD_TARGET}
```

I hope this small repo will help you in case if you'll decide to develop the Android u-boot.

Have a nice day! ))
