The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.

To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
Add support for SAMA5D2 ICP board.

Hardware:
- SoC: SAMAA5D27
- RAM: 512 MB DDR3L
- MMC: One stanard SD card interface
- USB: One USB host switch 4 ports with power switch,
       One USB device type Micro-AB
- CAN: 2 interfaces
- Ethernet: One Gigabit Ethernet PHY through HSIC,
	    One ETH switchport
	    One EtherCAT interface
- WiFi/BT: Footprint for IEEE 802.11 b/g/n Wi-Fi plus
	   Bluetooth module (Wi-Fi/BT), suitable for
	   Microchip WILC3000-MR110CA or WILC3000-MR110UA
- Debug port: One J-Link-OB/J-Link-CDC, one JTAG interface
- Leds: one RGB LED
- Buttons: reset, wakeup, 2 user buttons
- Expansion: one PIOBU/PIO connector, 3 mikrobus sockets
- Power mangament: PMIC (MCP16502), one power consumption device
                   (PAC1934)

Not working in Linux:
- EtherCAT interface: there is no Linux support integrated
- PAC1934: driver available at [1] but not integrated in Linux

Flashing:
- follow the procedure at [2]
