U-Boot has support for so-called standalone applications. These are programs that do not require the complex
environment of an operating system to run. Instead they can be loaded and executed by U-Boot directly,
utilizing U-Boot's service functions like console I/O or malloc() and free().
This can be used to dynamically load and run special extensions to U-Boot like special hardware test routines
or bootstrap code to load an OS image from some filesystem.
The go command is used to start such standalone applications. The optional arguments are passed to the
application without modification. For more informatoin see 5.12. U-Boot Standalone Applications.
