- [ ] I can reproduce the issue with unmodified Buildroot from [this
-      repository](https://gitlab.com/buildroot.org/buildroot), not from a
-      fork somewhere else
- [ ] I can reproduce the issue on the latest commit of the branch I'm using:
-    - [ ] master
-    - [ ] stable (i.e. 20NN.MM.x - please specify)
-    - [ ] LTS (i.e. 20NN.02.x - please specify)
- [ ] 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`)
- [ ] I attached a **minimal** defconfig file that can reproduce the
-      issue (`make BR2_DEFCONFIG=$(pwd)/issue_defconfig savedefconfig`)
- [ ] I also attached the configuration for kconfig-based packages that
-      are enabled (and necessary to reproduce the issue), most notably:
-    - [ ] busybox
-    - [ ] linux
-    - [ ] uclibc
-    - [ ] uboot
-    - [ ] …

-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.

+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
+├── rootfs.tar
+├── sdcard.img
+├── socfpga_cyclone5_socrates.dtb
+├── u-boot-spl.bin

+
+
+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.

+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

-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_ax45mp.dtb
-  |-- boot.vfat
-  |-- fw_dynamic.bin
-  |-- fw_dynamic.elf
-  |-- Image
-  |-- rootfs.ext2
-  |-- rootfs.ext4 -> rootfs.ext2
-  |-- sdcard.img
-  |-- u-boot-spl.bin
-  `-- u-boot.itb
-
-How to update the bootloader and device-tree
-============================================
-
-To update the bootloader and device tree, make sure you have
-an ICEman (Andes OpenOCD [1]) and AICE [2] connection set up
-as below:
-
-  Local Host                 Local/Remote Host
- .-----------------.          .--------------.
- | buildroot images|          |              |
- |                 |         ICEman host <IP:PORT>
- | .----------.    |          |  .--------.  |
- | | SPI_burn |<---+--socket--+->| ICEman |  |
- | '----------'    |          |  '--.-----'  |
- '-----------------'          '-----|--------'
-                                    |
-                                    USB
-   .--------------.                 |
-   | target       |           .-----v-----.
-   | board        <----JTAG---| AICE      |
-   |              |           '-----------'
-   '--------------'
-
-[1] https://github.com/andestech/ICEman
-[2] https://www.andestech.com/en/products-solutions/andeshape-platforms/aice-micro/
-
-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
-ae350_ax45mp.dtb: CONFIG_SYS_FDT_BASE=0x800f0000
-
-How to write the SD card
-========================
-
-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.

+Subject: [PATCH] nds32: Fix boot messages garbled
+
+In order to display uart correctly we have to pass the correct setting of uart to kernel by bootarg.
+This patch will provide such settings to set the correct uart baud rate.

+
+Andestech(nds32) AE3XX Platform
+
+The AE3XX prototype demonstrates the AE3XX example platform on the FPGA. 
+It is composed of one Andestech(nds32) processor and AE3XX.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+The andes_ae3xx_defconfig configuration is a sample configuration with
+all that is required to bring the FPGA Development Board:
+
+  $ make andes_ae3xx_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
+  $ target remote [your host]
+  $ lo

-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=2663527

-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-4.7/Foundation_Platform \
    --image output/images/linux-system.axf \
    --block-device output/images/rootfs.ext2 \
-    --network=nat \
-    --cores 4
+    --network=nat

 You can get network access from within the simulated environment
 by requesting an IP address using DHCP (run the command 'udhcpc').
