    Yes this is essentially the start of the sequence. Then also...

    • U-Boot also loads the device tree file (alongside with the Kernel) needed for the boot, in your case the dtb file for the AM335x Starter Kit
    • Kernel loads various drivers (modules) and firmwares as needed
    • Kernel loads and runs /sbin/init which is really the first process run by the system

    If you need any more details on any of those items a quick google search should produce a wealth of information, there is nothing "TI-special" really about the entire flow.
