[U-Boot] Internal Boot mode

[JYOTI DUBEY]

Can anybody tell what all happens inside an i.mx6 board when we try to boot
it in internal mode? Is it that in internal mode the board does not look
into the flash at all to discover the u-boot image and the image must be
provided only from the serial port? If yes then what steps should be
followed to perform internal booting? It would be of great help if commands
for performing internal booting is provided.

Thanks in Advance!
