+Enable FWU Multi Bank Update
+============================
+
+DeveloperBox supports the FWU Multi Bank Update. You *MUST* update both *SCP firmware* and *TF-A* for this feature. This will change the layout and the boot process but you can switch back to the normal one by changing the DSW 1-4 off.
+
+Configure U-Boot
+----------------
+
+To enable the FWU Multi Bank Update on the DeveloperBox, you need to add following configurations to configs/synquacer_developerbox_defconfig ::
+
+ CONFIG_FWU_MULTI_BANK_UPDATE=y
+ CONFIG_FWU_MDATA_MTD=y
+ CONFIG_CMD_FWU_METADATA=y
+ CONFIG_TOOLS_MKFWUMDATA=y
+
+And build it::
+
+  cd u-boot/
+  export ARCH=arm64
+  export CROSS_COMPILE=aarch64-linux-gnu-
+  make synqucer_developerbox_defconfig
+  make -j `noproc`
+  cd ../
+
+By default, the CONFIG_FWU_NUM_BANKS and COFNIG_FWU_NUM_IMAGES_PER_BANKS are set to 2 and 1 respectively. This uses FIP (Firmware Image Package) type image which contains TF-A, U-Boot and OP-TEE (the OP-TEE is optional.)
+You can use fiptool to compose the FIP image from those firmware images.
+
+Rebuild SCP firmware
+--------------------
+
+Rebuild SCP firmware which supports FWU Multi Bank Update as below::
+
+  cd SCP-firmware/
+  OUT=./build/product/synquacer
+  ROMFW_FILE=$OUT/scp_romfw/$SCP_BUILD_MODE/bin/scp_romfw.bin
+  RAMFW_FILE=$OUT/scp_ramfw/$SCP_BUILD_MODE/bin/scp_ramfw.bin
+  ROMRAMFW_FILE=scp_romramfw_release.bin
+
+  make CC=$ARM_EMB_GCC PRODUCT=synquacer MODE=release
+  tr "\000" "\377" < /dev/zero | dd of=${ROMRAMFW_FILE} bs=1 count=196608
+  dd if=${ROMFW_FILE} of=${ROMRAMFW_FILE} bs=1 conv=notrunc seek=0
+  dd if=${RAMFW_FILE} of=${ROMRAMFW_FILE} bs=1 seek=65536
+  cd ../
+
+And you can get the `scp_romramfw_release.bin` file
+
+Rebuild TF-A and FIP
+--------------------
+
+Rebuild TF-A which supports FWU Multi Bank Update as below::
+
+  cd arm-trusted-firmware/
+  make CROSS_COMPILE=aarch64-linux-gnu- -j`nproc` PLAT=synquacer \
+     SPD=opteed SQ_RESET_TO_BL2=1 GENERATE_COT=1 MBEDTLS_DIR=../mbedtls \
+     BL33=../u-boot/u-boot.bin all fip fiptool
+
+And make a FIP image.::
+
+  cp build/synquacer/release/fip.bin SPI_NOR_NEWFIP.fd
+  tools/fiptool/fiptool update --tb-fw build/synquacer/release/bl2.bin SPI_NOR_NEWFIP.fd
+
+
+UUIDs for the FWU Multi Bank Update
+-----------------------------------
+
+FWU multi-bank update requires some UUIDs. The DeveloperBox platform uses following UUIDs.
+
+ - Location UUID for the FIP image: 17e86d77-41f9-4fd7-87ec-a55df9842de5
+ - Image type UUID for the FIP image: 10c36d7d-ca52-b843-b7b9-f9d6c501d108
+ - Image UUID for Bank0 : 5a66a702-99fd-4fef-a392-c26e261a2828
+ - Image UUID for Bank1 : a8f868a1-6e5c-4757-878d-ce63375ef2c0
+
+These UUIDs are used for making a FWU metadata image.
+
+Generate FWU metadata image
+---------------------------
+
+Before installation, you need to generate a FWU metadata image file by mkfwumdata command as below::
+
+ tools/mkfwumdata -i 1 -b 2 "17e86d77-41f9-4fd7-87ec-a55df9842de5,10c36d7d-ca52-b843-b7b9-f9d6c501d108,5a66a702-99fd-4fef-a392-c26e261a2828,a8f868a1-6e5c-4757-878d-ce63375ef2c0" fwu-mdata.img
+
+Then, you can get the `fwu-mdata.img` image file.
+
+Install via flash writer
+------------------------
+
+As explained in above section, the new FIP image and the FWU metadata image can be installed via NOR flash writer. Note that the installation offsets for the FWU multi bank update supported firmware.
+
+Once the flasher tool is running we are ready flash the images. At first, please install FWU metadata at 0x500000 (primary) and 0x530000 (secondary).::
+
+  flash rawwrite 500000 60
+  >> Send fwu-mdata.img via XMODEM (Control-A S in minicom) <<
+
+  flash rawwrite 530000 60
+  >> Send fwu-mdata.img via XMODEM (Control-A S in minicom) <<
+
+And write the FIP image to the 0x600000 offset.::
+
+  flash rawwrite 600000 180000
+  >> Send SPI_NOR_NEWFIP.fd via XMODEM (Control-A S in minicom) <<
+
+And write the new SCP firmware.::
+
+  flash write cm3
+  >> Send scp_romramfw_release.bin via XMODEM (Control-A S in minicom) <<
+
+At last, turn on the DSW 3-4 on the board, and reboot.
+Note that if DSW 3-4 is turned off, the DeveloperBox will boot from
+the original EDK2 firmware (or non-FWU U-Boot if you already installed.)
