This is an API for external (standalone) applications running on top of U-Boot, and is meant to be more extensible and robust than the existing jumptable mechanism. It is similar to UNIX syscall approach. See api/README for more details. Included is the demo application using this new framework (api_examples). Please note this is still an experimental feature, and is turned off by default. Signed-off-by: Rafal Jaworowski <raj@semihalf.com>
