board: amlogic: move boards doc into doc/board/amlogic

Move the natural text Amlogic board README files to doc/board/amlogic
into reStructuredText and :
- add reStructuredText markup for bash code
- fix secondary titles markup
- move board support into global support matrix

+U-Boot for LibreTech CC
+=======================
+
+LibreTech CC is a single board computer manufactured by Libre Technology
+with the following specifications:
+
+ - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
+ - ARM Mali 450 GPU
+ - 2GB DDR3 SDRAM
+ - 10/100 Ethernet
+ - HDMI 2.0 4K/60Hz display
+ - 40-pin GPIO header
+ - 4 x USB 2.0 Host
+ - eMMC, microSD
+ - Infrared receiver
+
+Schematics are available on the manufacturer website.
+
+U-Boot compilation
+------------------
+
+.. code-block:: bash
+
+    $ export CROSS_COMPILE=aarch64-none-elf-
+    $ make libretech-cc_defconfig
+    $ make
+
+Image creation
+--------------
+
+To boot the system, u-boot must be combined with several earlier stage
+bootloaders:
+
+* bl2.bin: vendor-provided binary blob
+* bl21.bin: built from vendor u-boot source
+* bl30.bin: vendor-provided binary blob
+* bl301.bin: built from vendor u-boot source
+* bl31.bin: vendor-provided binary blob
+* acs.bin: built from vendor u-boot source
+
+These binaries and the tools required below have been collected and prebuilt
+for convenience at <https://github.com/BayLibre/u-boot/releases/>
+
+Download and extract the libretech-cc release from there, and set FIPDIR to
+point to the `fip` subdirectory.
+
+.. code-block:: bash
+
+    $ export FIPDIR=/path/to/extracted/fip
+
+Alternatively, you can obtain the original vendor u-boot tree which
+contains the required blobs and sources, and build yourself.
+Note that old compilers are required for this to build. The compilers here
+are suggested by Amlogic, and they are 32-bit x86 binaries.
+
+.. code-block:: bash
+
+    $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

+    $ cd amlogic-u-boot
+    $ make libretech_cc_defconfig
+    $ make
+    $ export FIPDIR=$PWD/fip
+
+Once you have the binaries available (either through the prebuilt download,
+or having built the vendor u-boot yourself), you can then proceed to glue
+everything together. Go back to mainline U-Boot source tree then :

+source code. Should you prefer to avoid that, there are open source reverse

+
+1. gxlimg <https://github.com/repk/gxlimg>, which comes with a handy
+   Makefile that automates the whole process.
+2. meson-tools <https://github.com/afaerber/meson-tools>
+
+However, these community-developed alternatives are not endorsed by or
+supported by Amlogic.

+ - Amlogic S905X3 ARM Cortex-A55 quad-core SoC
+ - 2GB DDR4 SDRAM
+ - 10/100 Ethernet (Internal PHY)
+ - 1 x USB 3.0 Host
+ - 1 x USB Type-C DRD
+ - 1 x FTDI USB Serial Debug Interface
+ - eMMC
+ - SDcard
+ - Infrared receiver
+ - SDIO WiFi Module
