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.
17 - To burn image to SD/eMMC device, the target is defined
20 Bubt command details (burn image step by-step)
21 ----------------------------------------------
24 1. Fetch the requested ATF image from an available interface (USB/SD/SATA/XDB, etc.)
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).
39   The boot partitions are numbered as partition 1 and 2 in MMC driver.
41   boot images and U-Boot environment in RAW mode since it will break file system
44   CONFIG_SYS_MMC_ENV_PART=1
45   Valid values for this parameter are 1 for BOOT0 and 2 for BOOT1.
47   The eMMC has 2 boot partitions (BOOT0 and BOOT1) and a user data partition (DATA).
48   The boot partitions are numbered as partition 1 and 2 in MMC driver.
50   boot images and U-Boot environment in RAW mode since it will break file system
53   CONFIG_SYS_MMC_ENV_PART=1
54   Valid values for this parameter are 1 for BOOT0 and 2 for BOOT1.
56 - The partition number is ignored if the target device is SD card.
57 - The boot image offset starts at block 0 for eMMC and block 1 for SD devices.
61 	- NAND:		# nand write <load_address> 0 <ATF Size>
62 	- SPI:		# sf write <load_address> 0 <ATF Size>
63 	- SD/eMMC:	# mmc write <load_address> [0|1] <ATF Size>/<block_size>
