* entry point is called early in the initialization -- after all memory
* has been configured and mapped but before any devices have been
* initialized.

* be called immediately after up_initialize() is called and just before
* the initial application is started. This additional initialization
* phase may be used, for example, to initialize board-specific device
* drivers.
