arm: add initial support for Amlogic Meson and ODROID-C2
This adds platform code for the Amlogic Meson GXBaby (S905) SoC and a board definition for ODROID-C2. This initial submission only supports UART and Ethernet (through the existing Designware driver). DTS files are the ones submitted to Linux arm-soc for 4.7 [1].

| U-Boot for ODROID-C2 | ||||
| ==================== | ||||
| 
 | ||||
| ODROID-C2 is a single board computer manufactured by Hardkernel | ||||
| Co. Ltd with the following specifications: | ||||
| 
 | ||||
|  - Amlogic S905 ARM Cortex-A53 quad-core SoC @ 2GHz | ||||
|  - 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. | ||||
| 
 | ||||
| Currently the u-boot port supports the following devices: | ||||
|  - serial | ||||
|  - Ethernet | ||||
| 
 | ||||
| u-boot compilation | ||||
| ================== | ||||
| 
 | ||||
|  > export ARCH=arm | ||||
|  > 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: | ||||
| 
 | ||||
|  > 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=$DIR/u-boot.gxbb bs=512 skip=96 | ||||
| 
 | ||||
| and then write the image to SD with: | ||||
| 
 | ||||
|  > DEV=/dev/your_sd_device | ||||
|  > BL1=$DIR/sd_fuse/bl1.bin.hardkernel | ||||
|  > dd if=$BL1 of=$DEV conv=fsync bs=1 count=442 | ||||
