+The aarch64_efi_defconfig allows to build a minimal Linux system that
+can boot on all AArch64 servers providing an EFI firmware and ACPI.
+
+Building and booting
+====================
+
+$ make aarch64_efi_defconfig
+$ make
+
+The file output/images/disk.img is a complete disk image that can be
+booted, it includes the grub2 bootloader, Linux kernel and root
+filesystem.
+
+Testing under Qemu
+==================
+
+This image can also be tested using Qemu:
+
+qemu-system-aarch64 \
+	-M virt \
+	-cpu cortex-a57 \
+	-m 512 \
+	-nographic \

+	-netdev user,id=eth0 \
+	-device virtio-net-device,netdev=eth0
+
+Note that </path/to/QEMU_EFI.fd> needs to point to a valid aarch64 UEFI
+firmware image for qemu.
+It may be provided by your distribution as a edk2-aarch64 or AAVMF
+package, in path such as /usr/share/edk2/aarch64/QEMU_EFI.fd .

+Amarula A64 Relic
+================
+
+Amarula A64-Relic is an Allwinner A64 based IoT device, which supports:
+- Allwinner A64 Cortex-A53
+- Mali-400MP2 GPU
+- AXP803 PMIC
+- 1GB DDR3 RAM
+- 8GB eMMC
+- AP6330 Wifi/BLE
+- MIPI-DSI
+- CSI: OV5640 sensor
+- USB OTG
+- 12V DC power supply
+
+Wiki link:
+https://openedev.amarulasolutions.com/display/ODWIKI/Amarual+A64-Relic
+
+Build
+=====
+
+  $ make amarula_a64_relic_defconfig
+
+  $ make
+
+build files at output/images/:
+  - sunxi-spl.bin
+  - u-boot.itb
+  - Image
+  - sun50i-a64-amarula-relic.dtb
+  - boot.vfat
+  - rootfs.ext4
+
+Write eMMC
+=========
+
+The board comes with an operating system preloaded on the eMMC.
+To replace it with the Buildroot-built system, take the following
+steps
+
+1. Connect the board UART with host and open minicom(ttyUSBx/115200N8)
+
+2. Supply 12V DC for power-on the board.
+
+3. Interrupt U-Boot by pressing enter
+
+4. Create GPT partitions
+  => mmc dev 1
+  => gpt write mmc 1 $partitions
+
+5. Connect the board USB-OTG with USB slot on the host.
+
+6. Initiate fastboot
+  => fastboot 0
+
+7. Write images from host onto eMMC using fastboot
+  $ cd output/images
+  $ sudo fastboot -i 0x1f3a flash loader1 sunxi-spl.bin
+  $ sudo fastboot -i 0x1f3a flash loader2 u-boot.itb
+  $ sudo fastboot -i 0x1f3a flash esp boot.vfat
+  $ sudo fastboot -i 0x1f3a flash system rootfs.ext4
+
+Update eMMC during Development
+==============================
+
+During development, reflashing the entire filesystem image at every
+change is time consuming. A useful alternative is to directly access
+over USB the filesystem stored on the eMMC, using the USB Mass Storage
+capability of U-Boot. To achieve this:
+
+1. Build U-Boot by enabling UMS
+   $ make uboot-menuconfig
+   (select CONFIG_CMD_USB_MASS_STORAGE=y)
+
+2. Follow all 6 steps from 'Write eMMC' and mount eMMC on host
+    => mmc dev 1
+    => ums 0 mmc 1

+============
+
+Vyasa is RK3288 based Single board computer with fully supported opensource software.
+
+https://openedev.amarulasolutions.com/display/ODWIKI/Vyasa+RK3288
+
+How to build it
+===============
+
+  $ make amarula_vyasa_rk3288_defconfig
+
+Then you can edit the build options using
+
+  $ make menuconfig
+
+Compile all and build rootfs image:
+
+  $ make
+
+Prepare your SDCard
+===================
+
+Buildroot generates a ready-to-use SD card image that you can flash directly to
+the card. The image will be in output/images/sdcard.img.
+You can write this image directly to an SD card device (i.e. /dev/xxx):
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/xxx
+  $ sudo sync
+
+Finally, you can insert the SD card to the Vyasa RK3288 board, close J4 and boot it.

+Arcturus uCLS1012A SoM
+======================
+
+This tutorial describes how to use the predefined Buildroot
+configuration for the Arcturus uCLS101A SoM platform.
+
+Additional information about the uCLS1012A System on Module can be found at
+https://www.arcturusnetworks.com/products/ucls1012a
+and product support for registered users at
+https://www.arcturusnetworks.com/support
+
+Building
+--------
+
+Return to the top directory <buildrootdir> and execute the following commands.
+
+  make arcturus_ucls1012a_defconfig
+  make
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- arc-ucls1012a.dtb
+    +-- Image
+    +-- part0-000000.itb
+    +-- rootfs.cpio
+    +-- rootfs.cpio.gz
+    +-- rootfs.tar
+    +-- u-boot.bin
+    +-- ucls1012a.its
+
+Flashing
+--------
+
+You'll need to program the image created by buildroot into the SPI NOR flash.
+
+1. Reboot your module and via the serial console press <escape> to enter the B$
+u-boot shell.
+   From the shell you will need to update four environment variables replacing the
+   IPv4 IP Address with ones that will work with your network and tftp server.
+
+   B$ setenv ipaddr 192.168.1.81
+   B$ setenv serverip 192.168.1.80
+   B$ setenv gatewayip 192.168.1.1
+   B$ setenv netmask 255.255.255.0
+   B$ saveenv
+
+2. Enable tftp server to serve the <buildrootdir>/output/images/ folder.
+
+3. Program the new U-Boot binary (optional)
+    If you don't feel confident upgrading your bootloader then don't do it,
+    it's unnecessary most of the time.
+
+    B$ tftp u-boot.bin
+    B$ run program_uboot
+
+4. Program the ITB image (includes Kernel, DTB and Ramdisk)
+
+    B$ tftp part0-000000.itb
+    B$ run iprogram
+
+5. Booting your new system
+
+    Reboot your system by reset command
+    B$ reset
+
+        or
+
+    B$ run bootcmd
+
+Good Luck !

+Intro
+=====
+
+This default configuration will allow you to start experimenting with the
+buildroot environment for the Bananapi M2 ULtra. With the current
+configuration it will bring-up the board, and allow access through the
+serial console.
+
+Bananapi M2 Ultra link:
+http://www.banana-pi.org/m2u.html
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+How to build
+============
+
+    $ make bananapi_m2_ultra_defconfig
+    $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+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
+  $ sudo sync
+
+Insert the micro SDcard in your Bananapi M2 Ultra and power it up. The console
+is on the serial line, 115200 8N1.

+Subject: [PATCH] mips: Remove default endiannes
+
+Currently, trying to build ci20_mmc fails on little-endian
+toolchains. The problem seems to be that some targets don't
+have CONFIG_SYS_LITTLE_ENDIAN properly set, and therefore
+the default -EB switch is selected.
+
+Let's get rid of the default switch entirely, and fix this problem.
+While this may be a hack, it is a quick solution until
+U-Boot gets CI20 proper support.

-Digilent Zybo
-=============
-
-This is the Buildroot board support for the Digilent Zybo. The Zybo is
-a development board based on the Xilinx Zynq-7000 based All-Programmable
-System-On-Chip.
-
-Zybo information including schematics, reference designs, and manuals are
-available from http://store.digilentinc.com/zybo-zynq-7000-arm-fpga-soc-trainer-board/ .
-
-If you want a custom FPGA bitstream to be loaded by U-Boot, copy it as
-system.bit in board/digilent/zybo/.
-
-Steps to create a working system for Zybo:
-
-1) make zynq_zybo_defconfig
-2) make
-3) write your SD Card with the sdcard.img file using dd by doing
-  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
-4) insert the SD Card and power up your Zybo
-5) Expect serial console on the second USB serial port exposed by the board
-
-The expected output:
-

-
-Resulting system
-----------------
-Once the build process is finished you will have an image called "sdcard.img"
-in the output/images/ directory.
-
-The first partition is a FAT32 partition created at the beginning of the SD Card
-that contains the following files :
-    /BOOT.BIN
-    /zynq-zybo.dtb
-    /uEnv.txt
-    /system.bit
-    /uImage
-    /u-boot-dtb.img
-
-The second partition is an ext4 partition that contains the root filesystem.
-
-You can alter the booting procedure by modifying the uEnv.txt file
-in first partition of the SD card. It is a plain text file in format
-<key>=<value> one per line:
-

+sudo dd if=output/images/sdcard.img of=/dev/<sdcard-block-device> bs=1M
+
+3. Running buildroot
+--------------------
+
+Position the board so you can read the label "RIoTboard" on the right
+side of SW1 DIP switches. Configure the SW1 swiches like this:
+
+1   0  1   0   0  1   0  1
+ON OFF ON OFF OFF ON OFF ON
+
+Now plug your prepared SD-card in slot J6. Connect a serial console
+(115200, 8, N, 1) to header J18. Connect a 5V/1A power supply to the
+board and enjoy.

+Date: Fri, 6 Apr 2018 17:11:27 -0700
+Subject: [PATCH] imx: Create distinct pre-processed mkimage config files
+
+Each imx image is created by a separate sub-make and during this process
+the mkimage config file is run though cpp.
+
+The cpp output is to the same file no matter what imx image is being
+created.
+
+This means if two imx images are generated in parallel they will attempt
+to independently produce the same pre-processed mkimage config file at
+the same time.
+
+Avoid the problem by making the pre-processed config file name unique
+based on the imx image it will be used in.  This way each image will
+create a unique config file and they won't clobber each other when run
+in parallel.
+
+This should fixed the build bug referenced in b5b0e4e3 ("imximage:
+Remove failure when no IVT offset is found").

+***************************
+Freescale i.MX8MQ EVK board
+***************************
+
+This file documents the Buildroot support for the Freescale i.MX8MQ
+EVK board.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX8MQ EVK board:
+
+  make freescale_imx8mqevk_defconfig
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - bl31.bin
+  - boot.vfat
+  - fsl-imx8mq-evk.dtb
+  - Image
+  - imx8-boot-sd.bin
+  - lpddr4_pmu_train_fw.bin
+  - rootfs.ext2
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - signed_hdmi_imx8m.bin
+  - u-boot.bin
+  - u-boot.imx
+  - u-boot-nodtb.bin
+  - u-boot-spl-ddr.bin
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD 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 SD card. Launch the following
+command as root:
+
+  dd if=output/images/sdcard.img of=/dev/<your-sd-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/common/imx/genimage.cfg.template_imx8.
+
+Boot the i.MX8MQ EVK board
+==========================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- Configure the switches as follows:
+SW801:	ON	ON	OFF	OFF
+SW802:	ON	OFF
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+  emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enable HDMI output
+==================
+
+To enable HDMI output at boot you must provide the video kernel boot
+argument.  To set the video boot argument from U-Boot run after
+stopping in U-Boot prompt:
+
+setenv mmcargs 'setenv bootargs console=${console} root=${mmcroot} video=HDMI-A-1:1920x1080-32@60'
+saveenv
+reset
+
+Change screen resolution to suit your connected display.
+
+Enjoy!

+Odroid XU-4 board with Samsung Exynos 5422 SoC
+
+How to build it
+===============
+
+  $ make odroidxu4_defconfig
+
+Then you can edit the build options using
+
+  $ make menuconfig
+
+Compile all and build rootfs image:
+
+  $ make
+
+Note: you will need to have access to the network, since Buildroot will
+download the packages' sources.
+
+Result of the build
+-------------------
+
+After building, you should obtain all output files in output/images/
+
+
+How to write the SD card or eMMC
+================================
+
+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 or eMMC with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Insert the SDcard into your ODROID-XU4, and power it up. Your new system
+should come up now.

-From: David Lechner <david@lechnology.com>
-Date: Sun, 19 Nov 2017 19:54:32 -0600
-Subject: [PATCH] configs: legoev3: increase flash image sizes
-
-This increases the kernel image to 4M and the rootfs image to 10M.
-
-It is getting hard to get a kernel image to fit in 3M and the rootfs image
-size now matches the filesyssize variable.

+A10-OLinuXino-LIME
+
+Intro
+=====
+
+These are open hardware boards, all based on the Allwinner A10 SoC.
+
+for more details about the boards see the following pages:
+ - https://www.olimex.com/Products/OLinuXino/open-source-hardware
+ - https://www.olimex.com/Products/OLinuXino/A10/A10-OLinuXino-LIME/
+
+The following defconfigs are available:
+ - olimex_a10_olinuxino_lime_defconfig
+   for the A10-OLinuXino-LIME board using mainline kernel
+
+(see http://linux-sunxi.org/Linux_Kernel for more details)
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make <board>_defconfig
+
+Compile everything and build the rootfs image:
+
+    $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+    output/images/
+    +-- boot.scr
+    +-- rootfs.ext2
+    +-- rootfs.ext4 -> rootfs.ext2
+    +-- sdcard.img

+    +-- u-boot.bin
+    +-- u-boot-sunxi-with-spl.bin
+    `-- zImage
+
+
+How to write the SD card
+========================
+
+The sdcard.img file is a complete bootable image ready to be written
+on the boot medium. To install it, simply copy the image to a uSD
+card:
+
+    # dd if=output/images/sdcard.img of=/dev/sdX
+
+Where 'sdX' is the device node of the uSD.
+
+Eject the SD card, insert it in the A10-OLinuXino board, and power it up.
