[3rdparty][PATCH v2][master 4/4] ccimx6ulsbcexpress: Add initial board configuration

Alex Gonzalez

The ConnectCore 6UL Single Board Computer (SBC) Express contains the
ConnectCore 6UL System-On-Module.

Its hardware specifications are:

* 256MB DDR3 memory
* 256MB NAND flash
* Single Ethernet
* USB Host and USB-OTG
* MicroSD external storage
* Groove connectors and Raspberry Pi Hat compatible expansion heade

The build artifacts are:

U-Boot images: u-boot.imx
Linux partition image: <image name>.boot.ubifs
Root filesystem image: <image name>.ubifs

Root filesystem tarball (for network booting): <image name>.tar.bz2

To program a board from the U-boot prompt, copy the U-Boot, Linux and
root filesystem partition images to your TFTP server root and do:

env set ipaddr <target ip address>
env set serverip <TFTP server ip address>
update uboot tftp u-boot.imx
update linux tftp <image name>.boot.ubifs
update rootfs tftp <image name>.ubifs

The ConnectCore 6UL SBC Express includes a ConnectCore 6UL
System-On-Module with the following specification:

* Based on a NXP i.MX6UL SoC
* Industrial temperature ranges (-40ºC to +85ºC)
* Up to 1GB DDR3 memory
* Up to 2GB NAND flash
* Dual Ethernet
* On module 802.11 WiFi and Bluetooth 4.2 (QCA6564)
* On module NXP Kinetis KL03
* On module Microchip ATECC508A crypto element
