U-Boot Falcon Mode
====================

Introduction
------------

This document provides an overview of how to add support for Falcon Mode
to a board.

Falcon Mode is introduced to speed up the booting process, allowing
to boot a Linux kernel (or whatever image) without a full blown U-Boot.

Falcon Mode relies on the SPL framework. In fact, to make booting faster,
U-Boot is split into two parts: the SPL (Secondary Program Loader) and U-Boot
image. In most implementations, SPL is used to start U-Boot when booting from
