 ===== How to build u-boot with bl301 firmware =====
-[ Under Construction :) ]
+Because of the issue of build failure on any platform other than x86-64 and support of buildroot, we've separated bl301 firmware source code from u-boot repository.
-=== Download and Build Guide ===
+In the path, u-boot/fip/gxb/, there is a pre-built bl301.bin binary of the latest version, so you can build just u-boot without a re-build bl301 process.
+If you want to modify and update bl301-related source codes by yourself, please refer to the following.
+=== Checkout and Merge ===
 You can checkout **bl301 firmware** source tree from **[[https://github.com/hardkernel/u-boot_firmware/tree/odroidc2-bl301|Hardkernel's Github]]**.

 $ git clone https://github.com/hardkernel/u-boot_firmware.git -b odroidc2-bl301
 </code>
+You should merge bl301 with u-boot before build it.
+<code>
+$ git clone https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01
+$ git clone https://github.com/hardkernel/u-boot_firmware.git -b odroidc2-bl301
+$ cd u-boot
+$ git remote add u-boot_firmware ../u-boot_firmware/
+$ git fetch u-boot_firmware
+$ git merge --no-commit u-boot_firmware/odroidc2-bl301
