 Changes v1->v2
  - No change
 Changes v2->v3 (Suggested by Arnout)
  - Remove uImage and add fitImage generation
  - Tidy readme.txt
  - Tidy ci40_defconfig, remove custom toolchain and add wifi helper packages
  Some changes are not done:
  - Using git-helper:
    - Custom kernel doesnt provide tar file, so it didnt work for me
 Changes v3->v4 (Suggested by Arnout)
  - Use github helper for getting kernel/u-boot
  - rename fitImage.its -> fitImage.its.in to reflect as template file,
    remove hardcoded dtb filename
  - Find dtb file in output/images directory and use first dtb in fitImage
  - Remove image size from genimage.cfg
  - Tidy readme.txt and add section to explain how to stop u-boot autoboot,
    how to make it persistent, and other grammar
 Changes v4->v5 (Suggested by Thomas)
  - Use fixed kernel entry addr
  - Generate vmlinux.bin.gz from generate vmlinux.bin
  - Remove generating uImage (not required for anything now)
 Changes v5->v6
  - Use kernel generate fitimage
  - bump up u-boot version
  - Change emailid from imgtec.com -> personal id
 Changes v6->v7 (Suggested by Thomas)
  - Use genimage.sh script
  - Improve and fix grammer in readme.txt
 Changes v7->v8 (Suggested by Arnout)
  - Use genimage.sh script from POST_IMAGE_SCRIPT
  - Use uboot kconfig base config
  - Remove dts config from defconfig
  - Some other small cleanup
  - rebase on master
 Changes v8->v9 (Suggested by Arnout)
  - Use sh instead of bash where bash feature is not needed
  - Use sudo for command run on user PC
  - Update bootloader flashing help text in readme.txt
 Changes v9->v10
  - No changes

+*********************
+* MIPS Creator CI40 *
+*********************
+
+This document details how to build and run a Buildroot system on the
+MIPS Creator CI40 platform. For more details about the CI40, see
+https://creatordev.io/ci40-iot-hub.html.
+
+How to build
+------------
+
+$ make ci40_defconfig
+$ make
+
+Prepare USB/MMC for boot
+------------------------
+
+On successful build, "sdcard.img" file will be created in 'output/images'
+folder.
+
+Use following command to write image to bootable device
+
+$ sudo dd if=./output/images/sdcard.img of=/dev/<your-microsd-or-usb-device>
+
+Booting from USB/MMC
+--------------------
+
+The boot loader is already present in NOR flash. To boot your newly generated
+Linux and root filesystem, you need to interrupt U-Boot autoboot. Current
+U-Boot is configured with 2 seconds of boot-delay, after expiry of this
+boot-delay timeout U-Boot starts booting the default image. To interrupt
+autoboot, press any key before the boot-delay time expires, U-Boot will
+stop the autoboot process and give a U-Boot prompt. You can now boot to
+your preferred boot method as describe below:
+
+From USB
+  pistachio # run usbboot
+
+From SD-Card
+  pistachio # run mmcboot
+
+Persistent boot command
+-----------------------
+
+To boot automatically to your preferred boot method, use following command to
+make it persistent, for example to automatically boot to usb:
+
+  pistachio # setenv bootcmd run usbboot
+  pistachio # saveenv
+
+Flash new bootloader
+--------------------
+
+The bootloader image will be available in the 'output/images' folder. To flash
+the new bootloader, copy it to the device and use the following command on the
+device:
+
+# flashcp -v u-boot-pistachio_marduk-<version>.img /dev/mtd0
+
+Online docs
+-----------
+
+Mostly for OpenWRT but it is applicable to Buildroot
+https://docs.creatordev.io/ci40/guides/openwrt-platform/#overview
