+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
typo CONFIG_
