-The aarch64_efi_defconfig allows to build a minimal Linux system that
-can boot on all AArch64 servers providing an EFI firmware.
-
-This includes all Arm EBBR[1] compliant systems, and all Arm SystemReady[2]
-compliant systems for example.
-
-
-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 \
-	-bios </path/to/QEMU_EFI.fd> \
-	-drive file=output/images/disk.img,if=none,format=raw,id=hd0 \
-	-device virtio-blk-device,drive=hd0 \
-	-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 .
-
-U-Boot based qemu firmware
-==========================
-
-A qemu firmware with support for UEFI based on U-Boot can be built following
-the instructions in [3], with qemu_arm64_defconfig.
-
-This should give you a nor_flash.bin, which you can use with qemu as an
-alternative to QEMU_EFI.fd. You will also need to change the machine
-specification to "-M virt,secure=on" on qemu command line, to enable TrustZone
-support, and you will need to increase the memory with "-m 1024".

-Acme Systems Acqua A5
-
-Intro
-=====
-
-The Acqua A5 is a system on module based on the Microchip SAMA5D31 SoC:
-
-    https://www.acmesystems.it/acqua
-
-The files here support configurations that build a microSD image for a
-minimal system that can be accessed through the serial console. You will
-need an USB-to-serial interface in order to access that console from
-your computer:
-
-    https://www.acmesystems.it/DPI
-
-How to build the image
-======================
-
-If you have an Acqua module with 256 MiB of RAM, type:
-
-$ make acmesystems_acqua_a5_256mb_defconfig
-
-If you have the 512 MiB version, type instead:
-
-$ make acmesystems_acqua_a5_512mb_defconfig
-
-You can optionally tweak the configuration and add packages by typing:
-
-$ make menuconfig
-
-Then, proceed with the build:
-
-$ make
-
-How to write the microSD card
-=============================
-
-The system image is the file "sdcard.img" in the "output/images"
-directory. Write it to the card by invoking:
-
-$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M
-
-where `sdX' is the block device representing the microSD card.

-Vyasa RK3288
-============
-
-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.

-Intro
-=====
-
-Andestech AE350 Platform
-
-The AE350 prototype demonstrates the AE350 platform on the FPGA.
-
-How to build it
-===============
-
-Configure Buildroot
--------------------
-
-  $ make andes_ae350_45_defconfig
-
-If you want to customize your configuration:
-
-  $ make menuconfig
-
-Build everything
-----------------
-Note: you will need to access to the network, since Buildroot will
-download the packages' sources.
-
-  $ make
-
-Result of the build
--------------------
-
-After building, you should obtain the following files:
-
-  output/images/
-  |-- ae350.dtb
-  |-- boot.vfat
-  |-- fw_dynamic.bin
-  |-- fw_dynamic.elf
-  |-- fw_jump.bin
-  |-- fw_jump.elf
-  |-- Image
-  |-- rootfs.ext2
-  |-- rootfs.ext4 -> rootfs.ext2
-  |-- sdcard.img
-  |-- u-boot-spl.bin
-  `-- u-boot.itb
-
-Copy the sdcard.img to a SD card with "dd":
-
-  $ sudo dd if=sdcard.img of=/dev/sdX bs=4096
-  $ sudo sync
-
-Your SD card partition should be:
-
-  Disk /dev/sdb: 14.48 GiB, 15552479232 bytes, 30375936 sectors
-  Disk model: Multi-Card
-  Units: sectors of 1 * 512 = 512 bytes
-  Sector size (logical/physical): 512 bytes / 512 bytes
-  I/O size (minimum/optimal): 512 bytes / 512 bytes
-  Disklabel type: dos
-  Disk identifier: 0x00000000
-
-  Device     Boot Start    End Sectors Size Id Type
-  /dev/sdb1           1   4096    4096   2M  c W95 FAT32 (LBA)
-  /dev/sdb2  *     4097 126976  122880  60M 83 Linux
-
-Insert SD card and reset the board, it should boot Linux from mmc.

-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.gz
-    +-- part0-000000.itb
-    +-- rootfs.cpio
-    +-- rootfs.cpio.gz
-    +-- rootfs.tar
-    +-- u-boot.bin
-    +-- br2-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 !

+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)
+  - Juno r2 (Big Cluster with A72)
+
+Buildroot will generate the kernel image, device tree blob, bootloader binaries
+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)
+    +-- juno-r2.dtb (if Juno r2 is used)
+    +-- Image
+    +-- bl1.bin
+    +-- bl2.bin
+    +-- bl2u.bin
+    +-- bl31.bin
+    +-- fip.bin
+    +-- scp-fw.bin
+    +-- u-boot.bin
+
+Preparing your rootfs
+======================
+
+Format your pen drive as a ext3 filesystem by executing:
+
+   $ mkfs.ext3 /dev/<your device>
+
+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), 'juno.dtb' (r0) or juno-r2.dtb (r2) file to software/
+6. Copy the bootloader binaries (bl1.bin and fip.bin) to software/
+7. 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.

-     expansion connector
-
- (4) Plug in power cable
-
- (5) The system will start, with the console on UART, but also visible
-     on the screen.

-Aspeed AST2500 EVB
-
-Introduction
-============
-
-The AST2500 EVB is an evaluation board for the AST2500 SoC, most
-commonly used as a Server Management Processor. It includes an 800MHz
-ARM11 processor with DDR3 or DDR4 SDRAM (up to 1GB), SPI flash memory
-devices for BMC and host firmwares and numerous controllers to drive
-the server board.
-
-  https://www.aspeedtech.com/server_ast2500/
-
-How to build it
-===============
-
-Configure buildroot:
-
-  $ make aspeed_ast2500evb_defconfig
-
-Compile everything and build the rootfs image:
-
-  $ make
-
-Result of the build
-===================
-
-After building, the output/images directory contains:
-
-  output/images/
-    ├── aspeed-ast2500-evb.dtb
-    ├── flash.img
-    ├── image.itb
-    ├── rootfs.cpio
-    ├── rootfs.cpio.xz
-    ├── rootfs.tar
-    ├── u-boot.bin
-    └── zImage
-
-Flashing the image
-==================
-
-To update the contents of the first flash device, copy flash.img :
-
-  $ flashcp flash.img /dev/mtd0
-
-or simply the boot loader:
-
-  $ flashcp u-boot.bin /dev/mtd1
-
-Preparing the board
-===================
-
- * Connect a serial line to the board
- * Power-up the board
-
-Booting the board
-=================
-
-The AST2500 EVB boots from the SPI flash device directly and loads a
-first bootloader (usually U-Boot). U-Boot will attempt to load a Linux
-kernel from the same flash device by default but other storage could
-be used.
-
- * from U-Boot

-Tinker RK3288
-=============
-
-Tinker Board is a Single Board Computer (SBC) in an ultra-small form
-factor that offers class-leading performance while leveraging outstanding
-mechanical compatibility.
-
-Tinker link:
-https://www.asus.com/in/Single-Board-Computer/Tinker-Board/
-
-Wiki link:
-https://openedev.amarulasolutions.com/display/ODWIKI/Tinker+RK3288
-
-How to build it
-===============
-
-  $ make asus_tinker_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 Tinker RK3288 board and boot it.
