+ Synopsis
+ --------
+ 
+ ::
+ 
+     ebtupdate [<bct> [<ebt>] [<size>]]
+ 
+ Description
+ -----------
+ 
+ The "ebtupdate" command is used to self-update bootloader on Tegra 2 and Tegra 3
+ production devices which were processed using re-cryption.
+ 
+ The "ebtupdate" performs encryption of new bootloader and decryption, patching
+ and re-encryption of BCT "in situ". After BCT and bootloader can be written in
+ their respective places.
+ 
+ bct
+     address of BCT block pre-loaded into RAM.
+ 
+ ebt
+     address of the bootloader pre-loaded into RAM.
+ 
+ size
+     size of the pre-loaded bootloader.
+ 
+ Example
+ -------
+ 
+ This is the boot log of a LG Optimus Vu:
+ 
+ ::
+ 
+     => mmc dev 0 1
+     switch to partitions #1, OK
+     mmc0(part 1) is current device
+     => mmc read $kernel_addr_r 0 $boot_block_size
+     MMC read: dev # 0, block # 0, count 4096 ... 4096 blocks read: OK
+     => load mmc 0:1 $ramdisk_addr_r $bootloader_file
+     684783 bytes read in 44 ms (14.8 MiB/s)
+     => size mmc 0:1 $bootloader_file
+     => ebtupdate $kernel_addr_r $ramdisk_addr_r $filesize
+     => mmc dev 0 1
+     switch to partitions #1, OK
+     mmc0(part 1) is current device
+     => mmc write $kernel_addr_r 0 $boot_block_size
+     MMC write: dev # 0, block # 0, count 4096 ... 4096 blocks written: OK
+     => mmc dev 0 2
+     switch to partitions #2, OK
+     mmc0(part 2) is current device
+     => mmc write $ramdisk_addr_r 0 $boot_block_size
+     MMC write: dev # 0, block # 0, count 4096 ... 4096 blocks written: OK
+ 
+ Configuration
+ -------------
+ 
+ The ebtupdate command is only available if CONFIG_CMD_EBTUPDATE=y and
+ only on Tegra 2 and Tegra 3 configurations.
+ 
+ Return value
+ ------------
+ 
+ The return value $? is set to 0 (true) if everything went successfully. If an
+ error occurs, the return value $? is set to 1 (false).
