6 bubt [file-name] [destination [source]]
7 	- file-name		Image file name to burn. default = flash-image.bin
8 	- destination		Flash to burn to [spi, nand, mmc]. default = active flash
9 	- source		Source to load image from [tftp, usb]. default = tftp
12 	bubt				- Burn flash-image.bin from tftp to active flash
13 	bubt latest-spi.bin nand	- Burn latest-spi.bin from tftp to NAND flash
16 - For the TFTP interface set serverip and ipaddr.

20 Bubt command details (burn image step by-step)

32 	- NAND:		# nand erase 0 100000
33 	- SPI:		# sf probe 0
35 	- SD/eMMC:	# mmc dev <dev_id> <boot_partition>
38 - The eMMC has 2 boot partitions (BOOT0 and BOOT1) and a user data partition (DATA).
41   boot images and U-Boot environment in RAW mode since it will break file system
47 - The partition number is ignored if the target device is SD card.
48 - The boot image offset starts at block 0 for eMMC and block 1 for SD devices.
52 	- NAND:		# nand write <load_address> 0 <ATF Size>
53 	- SPI:		# sf write <load_address> 0 <ATF Size>
54 	- SD/eMMC:	# mmc write <load_address> [0|1] <ATF Size>/<block_size>
