Add support for arm Juno Development Board

Add Yocto support for Juno development board:
- add machine definition
- add kernel configuration
- add u-boot patch to get the environment from a file in flash
- add trusted firmware extension to produce a firmware image
- add ifupdown interfaces to start eth0 and eth1 on startup

+# Juno Development Platform Support in meta-arm-platforms
+
+## Howto Build and Run
+
+### Configuration:
+In the local.conf file, MACHINE should be set as follow:
+MACHINE ?= "juno"
+
+### Build:
+```bash$ bitbake core-image-minimal```
+
+### Update Juno SD card:
+
+The SD card content is generated during the build here:
+tmp/deploy/images/juno/juno-oe-uboot.tar.gz
+
+Its content must be written on the Juno firmware SD card.
+To do this:
+- extract the content of the tar file:
+```bash$ tar -xzf tmp/deploy/images/juno/juno-oe-uboot.tar.gz```
+
+- insert the sdcard of the Juno in an SD card reader and mount it:
+```bash$ sudo mount /dev/sdx1 /mnt```
+(replace sdx by the device of the SD card)
+
+- erase its content and put the new one:
+```bash$ sudo rm -rf /mnt/*```
+```bash$ sudo cp -rf juno-oe-uboot/* /mnt/.```
+```bash$ sudo umount /mnt```
+
+- reinsert the SD card in the Juno board
+
+### Create an USB hard drive:
+
+Linux root file system should be stored on the second partition of an USB
+drive that must be plugged on the Juno Platform.
+
+This partition should be initialized with the content of the filesystem
+generated by yocto that you can find here:
+tmp/deploy/images/juno/core-image-minimal-juno.tar.bz2
+
+To do this
+- Format a USB disk, create two primary partitions (ext4).
+- mount the secondary partition
+- untar tmp/deploy/images/juno/core-image-minimal-juno.tar.bz2 on to the
+  secondary partition.
+
+### Run:
+You must insert the SD card and the USB drive and power-on the Juno board.
+The console should be available on the second serial line:
+screen -L /dev/tty.usbserial 115200
+
+On the first boot the images will be flashed which can take some time.
+
+## Devices supported in the kernel
+- serial
+- usb
+- network
+- watchdog
+- rtc
+- mmc
+
+### Untested:
+- i2c
+- dma
+- pci
+- sata
+- sound
+
+## Devices not supported or not functional
+- framebuffer: not functional
+    The HDMI is not properly detected.
+- GPU (no user land libraries).
+    The mali-midgard-kernel can be used to have a kernel driver
