U-boot is usable with proprietary operating system

I think to use bin file: in particular i refer to file produced by mkimage

command (specifying standalone type, arm architecture, uncompress and so

on).

Can it be a good idea?

After U-Boot jump to kernel entry point, what are main operation to

initialize and start kernel?

I'm using a cubietruck (with Cortex A-7).

Thanks in advance
