Christian Hewitt 9c84c21009 boards: amlogic: add Khadas VIM3L support
Khadas VIM3L uses the same board layout as VIM3, but with an S905D3 chip
instead of A311D. Board config is derived from khadas-vim3_defconfig and
sei610_defconfig. README is based on README.khadas-vim3; the difference
is that VIM3L uses FIP files from the g12a folder in vendor sources not
the g12b folder.

U-Boot for Amlogic W400
=======================

U200 is a reference board manufactured by Amlogic with the following
specifications:

 - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
 - 2GB DDR4 SDRAM
 - 10/100 Ethernet (Internal PHY)
 - 1 x USB 3.0 Host
 - eMMC
 - SDcard
 - Infrared receiver
 - SDIO WiFi Module
 - MIPI DSI Connector
 - Audio HAT Connector
 - PCI-E M.2 Connector

Schematics are available from Amlogic on demand.

Currently the u-boot port supports the following devices:
 - serial
 - Ethernet
 - Regulators
 - Clock controller

u-boot compilation
==================

 > export ARCH=arm
 > export CROSS_COMPILE=aarch64-none-elf-
 > make w400_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:

 > wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz

 > git clone https://github.com/BayLibre/u-boot.git -b buildroot-openlinux-20180418 amlogic-u-boot
 > cd amlogic-u-boot
 > make g12b_w400_v1_defconfig
 > make
 > export UBOOTDIR=$PWD

Download the latest Amlogic Buildroot package, and extract it :
 > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz
 > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader
 > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706
 > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip

Go back to mainline U-Boot source tree then :
 > mkdir fip
