No, currently not.

This is surely possible, though you might be better off with the U-Boot
code as a template for porting. You'll probably also need dos
partitioning support.

I think you don't need an extra command to do this once all necessary
code is in place. It's more a matter of a script like 'usb; mount -tfat
/dev/xxx /mnt; cp /mnt/xy /dev/nor0.kernel;'
We don't have this at the moment because nobody needed it yet. We mostly
use networking or dfu (device firmware update) for updating purposes.
That said patches are very welcome ;)
