+Acmesystems Arietta G25
+
+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Arietta G25. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+You can find additional informations, tutorials and a very comprehensive
+documentation on http://www.acmesystems.it/arietta.
+
+Build instructions
+==================
+
+To build an image for the arietta g25 choose the configuration
+corresponding to the arietta variant.
+
+For 128MB RAM variant type:
+
+$ make acmesystems_arietta_g25_128mb_defconfig
+
+else for 256MB RAM variant type:
+
+$ make acmesystems_arietta_g25_256mb_defconfig
+
+then:
+
+$ make
+
+How to write the microSD card
+=============================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Insert the microSD card into the arietta slot and power it.
+
+The image just built is fairly basic and the only output
+you will get is on serial console, please consider to use a DPI
+cable (http://www.acmesystems.it/DPI)

+ARM Juno r1/r0
+
+Intro
+=====
+
+These instructions apply to all models of the ARM Juno:
+  - Juno r0 (does not support PCIe)
+  - Juno r1 (supports PCIe)
+
+Buildroot will generate the kernel image, device tree blob and a
+minimal root filesystem.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+Configuring Buildroot is pretty simple, just execute:
+
+  $ make arm_juno_defconfig
+
+Build the rootfs, kernel and DTB
+--------------------------------
+
+Note: you will need to have access to the network, since Buildroot will
+download the packages' sources.
+
+You may now build your rootfs with:
+
+  $ make
+
+(This may take a while)
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- rootfs.tar
+    +-- juno.dtb (if Juno r0 is used)
+    +-- juno-r1.dtb (if Juno r1 is used)
+    +-- Image
+
+Preparing your rootfs
+======================
+
+Format your pen drive as a ext3 filesystem by executing:
+
+   $ mkfs.ext3 /dev/<your device>
+
+Installing your rootfs
+======================
+
+After mounting the pen drive please execute the following:
+
+   $ sudo tar -xvf output/images/rootfs.tar -C <pen drive mount path>
+
+When completed make sure to unmount the device:
+
+   $ umount <pen drive mount path>
+
+Insert the pen drive in one of the ARM Juno' USB type A connectors.
+
+Configure *.dtb in the boot configuration for Juno r0

+NOR3ENTRY: 00000000              ;Image Entry Point
+......
+
+Installing kernel image and DTB
+===============================
+
+1. Connect to the ARM Juno UART0 and execute USB_ON in the terminal
+2. Connect a USB cable between your PC and ARM Juno USB type B connector
+   A mass storage device should appear in your desktop.
+3. Open the software/ folder
+4. Copy the 'Image' file to software/
+5. Copy the 'juno-r1.dtb' (r1) or the 'juno.dtb' (r0) file to software/
+6. Press the red button in the front pannel of ARM Juno
+
+At this time, the board will erase the Flash entry for each new item and
+replace it with the lastest ones.

+***************************
+Freescale i.MX6UL EVK board
+***************************
+
+This file documents the Buildroot support for the Freescale i.MX6UL EVK board.
+
+Please read the i.MX6UL Evaluation Kit Quick Start Guide [1] for an
+introduction to the board.
+
+Build
+=====
+
+First, configure Buildroot for your i.MX6UL EVK board:
+
+  make freescale_imx6ulevk_defconfig
+
+Build all components:
+
+  make
+
+You will find in ./output/images/ the following files:
+  - imx6ul-14x14-evk.dtb
+  - rootfs.ext2
+  - rootfs.tar
+  - sdcard.img
+  - u-boot.imx
+  - zImage
+
+Create a bootable microSD card
+==============================
+
+To determine the device associated to the microSD card have a look in the
+/proc/partitions file:
+
+  cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a microSD card. Launch the following
+command as root:
+
+  dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/imx6ulevk/genimage.cfg.
+
+Boot the i.MX6UL EVK board
+=========================
+
+To boot your newly created system (refer to the i.MX6UL EVK Quick Start Guide
+[1] for guidance):
+- insert the microSD card in the microSD slot of the board;
+- verify that your i.MX6UL EVK board jumpers and switches are set as mentioned
+  in the i.MX6UL EVK Quick Start Guide [1];
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+  emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!

+Intel Galileo Gen 1/2
+
+Intro
+============
+
+These instructions apply to both the Intel Galileo Gen 1/2 development boards
+based on the Intel Quark X1000.
+
+How to build
+============
+
+Apply the defconfig for the Intel Galileo Gen 1/2
+
+ $ make galileo_defconfig
+
+Add any additional packages required and build.
+
+ $ make
+
+The build process will create a SD card image and place it in output/images.
+
+ $ ls -lh output/images/sdcard.img
+ -rw-r--r--. 1 foo foo 11M Nov 17 16:19 output/images/sdcard.img
+
+Write the image to an mSD card, insert into the Galileo and power on.
+
+ $ dd if=output/images/sdcard.img of=/dev/mmcblk0; sync
+
+Accessing the console
+=====================
+
+During power-on the console will become available on the Galileo's ttyS1. This 
+may be accessed as follows.
+
+ * Galileo Gen 1
+
+	http://clayskits.com/products/galileo-gen-1-serial-cable
+
+	A USB to RS-232 to 3.5mm Jack cable is required. Connect to the 3.5mm
+	Jack next to the Ethernet Header.
+
+ * Galileo Gen 2
+
+	http://www.ftdichip.com/Products/Cables/USBTTLSerial.htm
+
+	A FTDI TTL-232R-3V3 cable may be used to connect to the FTDI header 
+	next to the Ethernet connector on the Galileo Gen 2. 
+
+The console should now be visible at 115200 baud.

+OrangePi PC
+
+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the OrangePi PC. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make orangepipc_defconfig
+
+Compile everything and build the SD card image:
+
+    $ make
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX

-==================
+[2] This is the mkknlimg DT-marked kernel.
 
-For more information, visit
-http://elinux.org/RPi_Advanced_Setup#Advanced_SD_card_setup
+How to write the SD card
+========================
 
-In summary, your SDCard must have first partition in fat32 and marked bootable.
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
 
-Create the required partitions:
-  - for a persistent rootfs, 10MiB is enough memory for the boot fat32
-    partition, and a second partition is required for the root filesystem
-  - for a volatile rootfs, 50MiB is required for the boot fat32 partition
+Copy the bootable "sdcard.img" onto an SD card with "dd":
 
-Note: You can create any number of partitions you desire, the only requirement
-is that the first partition must be using fat32 and be bootable.
-
-Mount the partitions (adjust 'sdX' to match your SDcard device):
-
-  $ sudo mount /dev/sdX1 /mnt/mountpointboot
-  $ sudo mount /dev/sdX2 /mnt/mountpointroot    (only for persistent rootfs)
-
-Install the binaries to the SDCard
-----------------------------------
-
-At the root of the boot partition, the Raspberry Pi must find the following
-files:
-
-    * bcm2708-rpi-b.dtb         [2]
-    * bcm2708-rpi-b-plus.dtb    [3]
-    * bcm2709-rpi-2-b.dtb       [4]
-    * bootcode.bin
-    * config.txt
-    * fixup.dat
-    * start.elf
-    * zImage
-
-[2] For models A and B
-[3] For models A+ and B+
-[4] For model 2
-
-For example:
-
-  $ cp output/images/rpi-firmware/* /mnt/mountpointboot
-  $ cp output/images/*.dtb /mnt/mountpointboot
-
-The kernel image must be marked with a special header so that the
-bootloader of the RaspberryPi knows it supports Device Tree:
-
-  $ ./output/host/usr/bin/mkknlimg output/images/zImage /mnt/mountpointboot/zImage
-
-Note: The kernel image file name is defined in config.txt like this:
-kernel=zImage
-
-If you use a volatile rootfs, Skip to "Finish", below. For a persistent
-rootfs, there are further steps to do.
-
-Extract (as root!) the contents of the rootfs.tar archive into the second
-partition you created above:
-
-  $ sudo tar xf ./output/images/rootfs.tar -C /mnt/mountpointroot
