This patchset adds support for a ConnectCore 6UL SOM, based on NXP's i.MX6UL SoC, and SBC express board that uses it.

This initial patchset lacks support for the on-board WiFi and Bluetooth and the extended functionality provided by the on module NXP Kinetis KL03.

The ConnectCore 6UL uses a Digi vendor U-boot based on NXP's BSP U-Boot, and a linux-fslc mainline Linux kernel. The mainline support is lacking from
v4.18 but will be available in v4.19.

More information about the hardware can be found at:

ConnectCore 6UL SBC Express board:

This patchset has been tested agains the master branch. The following interfaces
have been verified:

* ADC
* SPI
* Ethernet
* GPIO
* NAND
* I2C
* PWM
* UART
* USB
* uSD

Changes from v1 [1]:

* Merged SOM and SBC machine configuration files into a single SBC file
* Use fix revision for u-boot-digi
