-- [ ] I can reproduce the issue after running `make clean; make`
-- [ ] I attached the full build log file (e.g. `make 2>&1 |tee build.log`)

+EBV SoCrates Evaluation Board
+
+Intro
+=====
+
+More information about this board can be found here:
+https://rocketboards.org/foswiki/Documentation/EBVSoCratesEvaluationBoard
+
+Build
+=====
+
+First, load socrates config for buildroot
+
+    make socrates_cyclone5_defconfig
+
+Build everything
+
+    make
+
+Following files will be generated in output/images
+
+.
+├── boot.vfat
+├── rootfs.ext2
+├── rootfs.ext4 -> rootfs.ext2

+
+
+Creating bootable SD card
+=========================
+
+Simply invoke
+
+dd if=output/images/sdcard.img of=/dev/sdX
+
+Where X is your SD card device (not partition)
+
+Booting
+=======
+
+Pins 6:8 on P18 selector is used to determine boot device. To boot socrates from
+sdcard set these pins to value 0x5 (101b). Remaining pins are used to determine
+how to configure FPGA and are not associated with booting into Linux kernel.

+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
+
+WiFi

+Subject: [PATCH] scripts/dtc: Remove redundant YYLOC global declaration
+
+gcc 10 will default to -fno-common, which causes this error at link
+time:
+
+  (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
+
+This is because both dtc-lexer as well as dtc-parser define the same
+global symbol yyloc. Before with -fcommon those were merged into one
+defintion. The proper solution would be to to mark this as "extern",
+however that leads to:
+
+  dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
+   26 | extern YYLTYPE yylloc;
+      |                ^~~~~~
+In file included from dtc-lexer.l:24:
+dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
+  127 | extern YYLTYPE yylloc;
+      |                ^~~~~~
+cc1: all warnings being treated as errors
+
+which means the declaration is completely redundant and can just be
+dropped.

+Andestech(nds32) AE300 Platform
+
+The AE300 prototype demonstrates the AE300 example platform on the FPGA.
+It is composed of one Andestech(nds32) processor and AE300.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+The andes_ae300_defconfig configuration is a sample configuration with
+all that is required to bring the FPGA Development Board:
+
+  $ make andes_ae300_defconfig
+
+Build everything
+----------------
+Note: you will need to have access to the network, since Buildroot will
+download the packages' sources.
+
+  $ make
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+output/images/
+    +-- vmlinux
+    +-- rootfs.cpio
+    +-- rootfs.tar
+
+How to run it
+=============
+
+Run
+---
+
+  Setup the Console with the rate 38400/8-N-1.
+
+  $ cd output/images
+  $ ../host/bin/nds32le-linux-gdb vmlinux

+Subject: [PATCH] Disable PIC explicitly for assembling

+This patch is necessary if the fw_dynamic load address
+is not equal to link address.
+However, they are equal currently, since we include an u-boot
+patch for preventing fw_dynamic relocation.

-The Andes SPI_burn tool will be located in output/host/bin. Use
-the following commands to update the bootloader and device tree:
-
-  $ SPI_burn --host $ICE_IP --port $ICE_BURNER_PORT --addr 0x0     -i u-boot-spl.bin
-  $ SPI_burn --host $ICE_IP --port $ICE_BURNER_PORT --addr 0x10000 -i u-boot.itb
-  $ SPI_burn --host $ICE_IP --port $ICE_BURNER_PORT --addr 0xf0000 -i ae350_ax45mp.dtb
-
-Note that the --addr option specifies the offset starting from
-the flash base address 0x80000000 and set by U-Boot configurations.
-e.g.
-u-boot-spl.bin  : CONFIG_SPL_TEXT_BASE=0x80000000
-u-boot.itb      : CONFIG_SPL_LOAD_FIT_ADDRESS=0x80010000

-Introduction
-============
-
 This is the support for the ARM Foundation v8 machine emulated by the
 ARM software simulator of the AArch64 architecture.
 
-Building
-========
+First, one has to download the AArch64 software simulator from:
 
-  $ make arm_foundationv8_defconfig
-  $ make
+  https://silver.arm.com/download/download.tm?pv=4807186
 
-Generated files under output/images:
-
-* linux-system.axf: An image comprising the boot-wrapper-aarch64 minimal
-                    firmware and bootloader, a Devicetree and the Linux kernel.
-* rootfs.ext2:      The OS root filesystem.
-
-Running on the simulator
-========================
-
-Download the AArch64 software simulator from one of the following sources,
-corresponding to your host computer:
-
-- https://developer.arm.com/-/cdn-downloads/permalink/FVPs-Architecture/FM-11.29/Foundation_Platform_11.29_27_Linux64.tgz
-- https://developer.arm.com/-/cdn-downloads/permalink/FVPs-Architecture/FM-11.29/Foundation_Platform_11.29_27_Linux64_armv8l.tgz
-
-The model will be located under one of the corresponding folders:
-
-- Foundation_Platformpkg/models/Linux64_GCC-9.3
-- Foundation_Platformpkg/models/Linux64_armv8l_GCC-9.3
+Then, use the arm_foundationv8_defconfig configuration to build your
+Buildroot system.
 
 Finally, boot your system with:
 
- Foundation_Platform \
-    --arm-v8.0 \
+ ${LOCATION_OF_FOUNDATIONV8_SIMULATOR}/models/Linux64_GCC-6.4/Foundation_Platform \
     --image output/images/linux-system.axf \
     --block-device output/images/rootfs.ext2 \

-Introduction
-============
-
-The arm_fvp_ebbr_defconfig is meant to illustrate some aspects of the Arm EBBR
-specification[1] and the Arm SystemReady Devicetree band[2].
-It allows building an AArch64 U-Boot based firmware implementing the subset of
-UEFI defined by EBBR, as well as a Linux OS disk image booting with UEFI, to run
-on the Arm A-Profile Base RevC AEM FVP.
-
-Building
-========
-
-  $ make arm_fvp_ebbr_defconfig
-  $ make
-
-Generated files under output/images:
-
-* bl1.bin: A ROM image built from TF-A.
-* fip.bin: A firmware image comprising TF-A, OP-TEE and the U-Boot bootloader.
-* disk.img: An OS disk image comprising the GRUB bootloader, the Linux kernel
-  and the root filesystem.
-
-Running on the FVP
-==================
-
-Download the FVP from one of the following sources, corresponding to your host
-computer:
-
-- https://developer.arm.com/-/cdn-downloads/permalink/FVPs-Architecture/FM-11.30/FVP_Base_RevC-2xAEMvA_11.30_27_Linux64.tgz
-- https://developer.arm.com/-/cdn-downloads/permalink/FVPs-Architecture/FM-11.30/FVP_Base_RevC-2xAEMvA_11.30_27_Linux64_armv8l.tgz
-
-The FVP will be located under one of the corresponding folders:
-
-- Base_RevC_AEMvA_pkg/models/Linux64_GCC-9.3
-- Base_RevC_AEMvA_pkg/models/Linux64_armv8l_GCC-9.3
-
-Run the simulation with:
-
-  FVP_Base_RevC-2xAEMvA \
-      --config-file board/arm/fvp-ebbr/fvp-config.txt \
-      -C bp.secureflashloader.fname="output/images/bl1.bin" \
-      -C bp.flashloader0.fname="output/images/fip.bin" \
-      -C bp.virtioblockdevice.image_path="output/images/disk.img"
-
-The login prompt will appear in a new X terminal.
-
-Using the EBBR firmware to run another OS on the FVP
-----------------------------------------------------
-
-It is possible to use the generated firmware binaries to run another OS
-supporting the EBBR specification.
-
-To run another OS on simulation using a live or pre-installed image, use the
-same FVP command line as for the generated OS but adapt the OS image path in the
-virtioblockdevice stanza.
-The image generated by the aarch64_efi_defconfig or the Arm ACS Devicetree
-images[3] are examples of pre-installed OS images.
-Linux distributions such as Debian, Fedora, openSUSE or Ubuntu, or FreeBSD
-provide live or pre-installed OS image.
-
-Firmware details
-================
-
-Noteworthy firmware features:
-
-- TF-A, OP-TEE & U-Boot
-- UEFI, with EFI variables stored on disk in the ESP
-- Support for ethernet, RTC and LCD
-
-Architecture diagram:
-
-                 Non-Secure          :   Secure

-       +----------------------------------------+
-
-Boot flow:
-
-  TF-A -+-> OP-TEE
-        `-> U-Boot -> GRUB -> Linux -> Busybox
-
-TF-A BL1 loads the fit image with the remaining pieces of TF-A, OP-TEE and
-U-Boot.
-OP-TEE boots, calls back TF-A to go to normal world.
-U-Boot loads GRUB with UEFI, boots Linux at EL2.
-
-In this configuration, the Devicetree is static and fully contained in TF-A.
-
-Miscellaneous
-=============
-
-This configuration is inspired by the arm_foundationv8_defconfig, the
-qemu_aarch64_virt_defconfig and the Arm SystemReady Devicetree Band Integration
-and Testing Guide[4].
-
-Firmware update, GOP, MMC and RNG are currently not supported.

+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>
+

+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.
