This commit introduces new subtarget for Marvell EBU Armada Cortex A53
processor based devices.

The first device is Globalscale ESPRESSObin. Some hardware specs:

SoC: Marvell Armada 3700LP (88F3720) dual core ARM Cortex A53
     processor up to 1.2GHz
RAM: 512MB, 1GB or 2GB DDR3
Storage: SATA interface
         µSD card slot with footprint for an optional 4GB EMMC
         4MB SPI NOR flash for bootloader
Ethernet: Topaz Networking Switch (88E6341) with 3x GbE ports
Connectors: USB 3.0
            USB 2.0
            µUSB port connected to PL2303SA (USB to serial bridge
            controller) for UART access
Expansion: 2x 46-pin GPIO headers for accessories and shields with
           I2C, GPIOs, PWM, UART, SPI, MMC, etc
           MiniPCIe slot
Misc: Reset button, JTAG interface

Currently booting only from µSD card is supported.
The boards depending on date of dispatch can come with various U-Boot
versions. For the newest version 2017.03-armada-17.10 no manual
intervention should be needed to boot OpenWrt image. For the older ones
it's necessary to modify default U-Boot environment:

 1. Interrupt boot process to run U-Boot command line,

 2. Run following commands:
    (for version 2017.03-armada-17.06 and 2017.03-armada-17.08)
     setenv bootcmd "load mmc 0:1 0x4d00000 boot.scr; source 0x4d00000"
     saveenv

    (for version 2015.01-armada-17.02 and 2015.01-armada-17.04)
     setenv bootargs "console=ttyMV0,115200 root=/dev/mmcblk0p2 rw rootwait"
     setenv bootcmd "ext4load mmc 0:1 ${fdt_addr} armada-3720-espressobin.dtb; ext4load mmc 0:1 ${kernel_addr} Image; booti ${kernel_addr} - ${fdt_addr}"
     saveenv

 3. Poweroff, insert SD card with OpenWrt image, boot and enjoy.

Adds support for the Turris Omnia and builds an eMMC sysupgrade image in
the same format as the SolidRun ClearFog.

An initramfs image in the simple yet Omnia-specific 'medkit' image format
is also built in order to ease the initial flashing process.

Notable hardware support omissions are support for switching between SFP
cage and copper PHY, and RGB LED control.

Due to a current limitation of DSA, only 1/2 CPU switch uplinks are used.

Specifications:
- Marvell Armada 385 1.6GHz dual-core ARMv7 CPU
- 1GB DDR3 RAM
- 8GB eMMC Flash
- 5x Gigabit LAN via Marvell 88E6176 Switch (2x RGMII CPU ports)
- 1x switchable RJ45 (88E1514 PHY) / SFP SGMII WAN
- 2x USB 3.0
- 12x dimmable RGB LEDs controlled by independent MCU
- 3x Mini PCIe slots
- Optional Compex WLE200N2 Mini PCIe AR9287 2x2 802.11b/g/n (2.4GHz)
- Optional Compex WLE900VX Mini PCIe QCA9880 3x3 802.11ac (2.4 / 5GHz)
- Optional Quectel EC20 Mini PCIe LTE modem

Flash instructions:
If the U-Boot environment has been modified previously (likely manually via
serial console), first use serial to reset the default environment.
=> env default -a
=> saveenv

Method 1 - USB 'medkit' image w/o serial
- Copy openwrt-mvebu-turris-omnia-sysupgrade.img.gz and
omnia-medkit-openwrt-mvebu-turris-omnia-initramfs.tar.gz to the root of a
USB flash drive formatted with FAT32 / ext2/3/4 / btrfs / XFS.
Note that the medkit MUST be named omnia-medkit*.tar.gz
- Disconnect other USB devices from the Omnia and connect the flash drive
to either USB port.
- Power on the Omnia and hold down the rear reset button until 4 LEDs are
illuminated, then release.
- Wait approximately 2 minutes for the Turris Omnia to flash itself with
the temporary image, during which LEDs will change multiple times.
- Connect a computer to a LAN port of the Turris Omnia with a DHCP client
- (if necessary) ssh-keygen -R 192.168.1.1
- ssh root@192.168.1.1
$ mount /dev/sda1 /mnt
$ sysupgrade /mnt/openwrt-mvebu-turris-omnia-sysupgrade.img.gz
- Wait another minute for the final OpenWrt image to be flashed. The Turris
Omnia will reboot itself and you can remove the flash drive.

Method 2 - TFTP w/ serial
- Extract omnia-medkit-openwrt-mvebu-turris-omnia-initramfs.tar.gz and copy
dtb + zImage to your TFTP server (rename if desired)
- Connect Turris Omnia WAN port to DHCP-enabled network with TFTP server
- Connect serial console and interrupt U-Boot
=> dhcp
=> setenv serverip <tftp_server_ip_here>
=> tftpboot 0x01000000 zImage
=> tftpboot 0x02000000 dtb
=> bootz 0x01000000 - 0x02000000
- OpenWrt will now boot from ramdisk
- Download openwrt-mvebu-turris-omnia-sysupgrade.img.gz to /tmp/
$ sysupgrade /tmp/openwrt-mvebu-turris-omnia-sysupgrade.img.gz
- Wait another minute for the final OpenWrt image to be flashed. The Turris
Omnia will reboot itself.
