+Pre-Generated FIP file set
+==========================
+
+The Amlogic ARMv8 based SoCs uses a vendor variant of the Trusted Firmware-A
+boot architecture.
+
+You can find documentation on the Trusted Firmware-A architecture on: https://www.trustedfirmware.org/projects/tf-a/
+
+The Trusted Firmware-A uses the following boot elements (simplified):
+
+- BL1: First boot step, implemented in ROM on Amlogic SoCs
+- BL2: Second boot step, used to initialize the SoC main clocks & DDR interface. The BL21 and ACS board-specific binaries are "inserted" in the BL32 binary before signing/packaging in order to be flashed on the platform.
+- BL30: Amlogic Secure Co-Processor (SCP) firmware used to handle all the system management operations (DVFS, suspend/resume, ...)
+- BL301: Amlogic Secure Co-Processor (SCP) board-specific firmware "plug-in" to handle custom DVFS & suspend-resume parameters
+- BL31: Initializes the interrupt controller and the system management interface (PSCI)
+- BL32 (Optional): Is the Trusted Environment Execution (TEE) Operating System to run secure Trusted Apps, e.g. OP-TEE
+- BL33: Is the last non-secure step, usually U-Boot which loads Linux
+
+Amlogic provides in binary form:
+
+- bl2.bin
+- bl30.bin
+- bl30.bin
+- bl31.img
+- bl32.bin
+
+And for lastest SoCs, Amlogic also provides the DDR drivers used by the BL2 binary.
+
+The licence of these files wasn't clear until recently, the currently Amlogic distribution licence
+is the following:
+
+.. code-block:: C

+
+The following files are generated from the Amlogic U-Boot fork:
+
+- acs.bin: contains the PLL & DDR parameters for the board
+- bl301.bin: contains the DVFS & suspend-resume handling code for the board
+- bl33.bin: U-boot binary image
+
+The acs.bin & bl301.bin uses the U-Boot GPL-2.0+ headers & build systems, thus those
+are considered issued from GPL-2.0+ source code.
+
+The tools used to sign & package those binary files are delivered in binary format
+for Intel x86-64 and Python 2.x only.
+
+A collection of pre-built with the corresponding Amlogic binaries for the common
+commercially available boards were collected in the https://github.com/LibreELEC/amlogic-boot-fip
+repository.
+
+Using this collection for a commercially available board is very easy.
+
+Here considering the Libre Computer AML-S905X-CC, which codename is `lepotato`:
+
+.. 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 lepotato /path/to/u-boot/u-boot.bin my-output-dir
+
+and then write the image to SD with:
+
+.. code-block:: bash
+
