Console Inc, an Android-based OS vendor, has started a new Github project for UEFI firmware for Android called AndCanGO:

AndCanGO: A project to unify the various UEFI & IA-capable fastboot and bootloaders, with its goal to deliver a custom, update-friendly Android recovery and GUI installer.

It is currently just created, an as-yet empty project. Watch for it to change in the upcoming days, along with some of their other related projects (which are not empty).
