Neil Armstrong 0ce3639d6f 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

- ARM Mali 450 GPU
- 2GB DDR3 SDRAM
- Gigabit Ethernet
- HDMI 2.0 4K/60Hz display
- 40-pin GPIO header
- 4 x USB 2.0 Host, 1 x USB OTG
- eMMC, microSD
- Infrared receiver
Schematics are available on the manufacturer website.
U-Boot compilation
------------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-none-elf-
$ make odroid-c2_defconfig
$ make
Image creation
--------------
Amlogic doesn't provide sources for the firmware and for tools needed
to create the bootloader image, so it is necessary to obtain them from
the git tree published by the board vendor:
.. code-block:: bash
$ DIR=odroid-c2
$ git clone --depth 1 \
https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01 \
$DIR
$ $DIR/fip/fip_create --bl30 $DIR/fip/gxb/bl30.bin \
--bl301 $DIR/fip/gxb/bl301.bin \
--bl31 $DIR/fip/gxb/bl31.bin \
--bl33 u-boot.bin \
$DIR/fip.bin
$ $DIR/fip/fip_create --dump $DIR/fip.bin
$ cat $DIR/fip/gxb/bl2.package $DIR/fip.bin > $DIR/boot_new.bin
$ $DIR/fip/gxb/aml_encrypt_gxb --bootsig \
--input $DIR/boot_new.bin \
--output $DIR/u-boot.img
$ dd if=$DIR/u-boot.img of=$DIR/u-boot.gxbb bs=512 skip=96
and then write the image to SD with:
.. code-block:: bash
$ DEV=/dev/your_sd_device
$ BL1=$DIR/sd_fuse/bl1.bin.hardkernel
$ dd if=$BL1 of=$DEV conv=fsync bs=1 count=442
$ dd if=$BL1 of=$DEV conv=fsync bs=512 skip=1 seek=1
$ dd if=$DIR/u-boot.gxbb of=$DEV conv=fsync bs=512 seek=97
