+U-Boot Compilation
+------------------
+
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-none-elf-
+    $ make beelink-gsking-x_defconfig
+    $ make
+
+U-Boot Signing with Pre-Built FIP repo
+--------------------------------------
+
+.. code-block:: bash
+    $ git clone https://github.com/LibreELEC/amlogic-boot-fip --depth=1
+    $ cd amlogic-boot-fip
+    $ mkdir my-output-dir
+    $ ./build-fip.sh beelink-s922x /path/to/u-boot/u-boot.bin my-output-dir
+
+U-Boot Manual Signing
+---------------------
+
+Beelink released an Amlogic "SDK" dump in their forums but the U-Boot sources included
+result in 2GB RAM detected. The following FIPs were generated with newer sources and
+detect 4GB RAM: https://github.com/LibreELEC/amlogic-boot-fip/tree/master/beelink-s922x
+
+.. code-block:: bash
+
+    $ wget https://github.com/LibreELEC/amlogic-boot-fip/archive/master.zip
+    $ unzip master.zip
+    $ export FIPDIR=$PWD/amlogic-boot-fip/beelink-s922x
+
+Go back to the mainline U-Boot source tree then:
