+=================================

+- Renesas R-Car E3 Ebisu board: https://elinux.org/R-Car/Boards/Ebisu
+
+Build U-Boot
+------------
+
+Please follow :doc:`Renesas 64-bit ARM SoC build environment setup <build-env-aarch64>`
+to correctly set up the build environment before attempting to build U-Boot.
+
+Clone up to date U-Boot source code and change directory into the
+newly cloned source directory:
+
+.. code-block:: console
+
+ $ git clone https://source.denx.de/u-boot/u-boot.git/
+ $ cd u-boot
+
+Configure U-Boot:
+
+.. code-block:: console
+
+ $ make r8a77990_ebisu_defconfig
+
+Compile U-Boot:
+
+.. code-block:: console
+
+ $ make
+
+To speed up build process, -jN option can be passed to make to start
+multiple jobs at the same time, this is beneficial especially on SMP
+systems. The following example starts up to number of CPUs in the
+system jobs, which is the recommended amount:
+
+.. code-block:: console
+
+ $ make -j$(nproc)
+
+Install U-Boot
+--------------
+
+Please follow :doc:`Renesas R-Car Gen3 U-Boot installation <rcar-gen3-install>`
+to install U-Boot into HyperFlash.
