-2018.08, Released September 6th, 2018
-
-	Minor fixes.
-
-	Known issues:
-
-	- Glibc 2.28 on the build host breaks compilation of a number
-	  of host packages. 2018.08 contains fixes for some of these
-	  packages, but not all. Consider building on hosts (or in
-	  containers) using older Glibc versions.
-
-	- host-dtc 1.4.7 breaks compilation of older U-Boot and Linux
-          kernel configurations using FDT/DTC. Consider updating the
-          Linux kernel to >= 4.17 and U-Boot to >= 2018.07 or
-          backporting commit 9130ba8846 (scripts/dtc: Update to
-          upstream version v1.4.6-9-gaadd0b65c987) for the Linux
-          kernel / commit db405d1980 for U-Boot.
-	  Alternatively revert commit 7b929ddcf0 (dtc: bump version to
-          1.4.7) and ensure your build host does not have the libfdt
-          development headers installed.

-
-2018.05-rc1, Released May 9th, 2018
-
-	Toolchain: glibc bumped to 2.27, musl bumped to 1.1.19,
-	uClibc-ng 1.0.30, Linux kernel headers bumped to 4.16.x.
-
-	Architecture: support for the Blackfin architecture has been
-	removed, as it was removed from Linux upstream, poorly
-	maintained in binutils/gdb, and abandoned by Analog Devices.
-
-	Numerous packages updated to have hashes for their license
-	files.
-
-	Systemd can now be built with uClibc toolchains.
-
-	Linux: addition of BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF and
-	BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL to support building Linux
-	kernel configurations that need libelf on the host or openssl
-	on the host.
-
-	Coding style:
-	- all Python scripts are now verified with flake8
-	- check-package extended to check all Config.in and .mk files
-	  in tree, not only the ones in package/
-
-	Infrastructure:
-
-	- The download infrastructure has seen a major overhaul, with
-	  the main visible new feature being Git caching: a package
-	  fetched from Git no longer needs to be re-cloned entirely
-	  everytime its version is changed. Anoter visible change is
-	  that the download folder now has subfolders per package. See
-	  http://lists.busybox.net/pipermail/buildroot/2018-April/217923.html
-	  for more details about those changes.
-
-	- The logic that generates the root filesystem images has been
-	  reworked, with the main goal of allowing several filesystem
-	  images to be produced in parallel, also a requirement for
-	  top-level parallel build. Now, a .tar filesystem image is
-	  always created, and re-extracted in a private directory to
-	  create each format-specific filesystem image.
-
-	- A new package infrastructure was introduced for Go-based
-	  packages: golang-package.
-
-	- Dependencies on extraction tools are now handled as proper
-	  per-package dependencies, using
-	  <pkg>_EXTRACT_DEPENDENCIES. Beyond a cleanup, this is also a
-	  preparation step for top-level parallel build support.
-
-	- When a file being downloaded is part of a package with a
-	  .hash file, but there is no hash listed for this file, the
-	  file is now preserved in the download directory rather than
-	  removed. This helps when updating a package, as it gives the
-	  ability to easily calculate the hash of the file.
-
-	- Addition of '<pkg>-show-recursive-depends' and
-	  '<pkg>-show-recursive-rdepends' make targets, to
-	  respectively display the recursive list of dependencies and
-	  the recursive list of reverse dependencies of a given
-	  package.
-
-	- The /etc/shells file is now automatically generated with the
-	  list of shell programs installed on the system.
-
-	- Addition of -Ofast optimization level as an available
-	  option.
-
-	Major updates: Go updated to 1.10, Erlang bumped to 20.3, Qt5
-	bumped to 5.10.1.
-
-	New packages: 18xx-ti-utils, abootimg, bluez-alsa, brotli,
-	chipmunk, clang, docker-compose, docker-proxy, flare-engine,

-	Toolchain: Workarounds for fix-rpath issues with binutils and
-	elf2flt.
-
-	Util-linux: Fix blocking on getrandom() issue with recent
-	kernels.

-
-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

-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
-

-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.

-Buildroot for Embest RIoTboard
-==============================
-
-This is a small development board, based on Freescale IMX6 Solo SoC
-(single core ARM Cortex-A9).
-
-More details about the board can be found at:
-
-  http://www.embest-tech.com/riotboard
-
-1. Compiling buildroot
----------------------
-
-$ make riotboard_defconfig
-$ make
-
-2. Installing buildroot
-----------------------
-
-Prepare an SD-card and plug it into your card reader. Always double
-check the block device before writing to it, as writing to the wrong
-block device can cause irrecoverable data loss. Now you can write the
-image to your SD-card:
-
-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.

+**************************************
+Freescale i.MX31 PDK development board
+**************************************
+
+This file documents the Buildroot support for the Freescale i.MX31 PDK in "3
+stack" configuration.
+
+The i.MX31 Product Development Kit (or PDK) is Freescale development board [1]
+based on the i.MX31 application processor [2].
+
+For more details on the i.MX31 PDK board, refer to the User's Guide [3].
+
+Build
+=====
+
+First, configure Buildroot for your i.MX31 PDK board:
+
+  make freescale_imx31_3stack_defconfig
+
+Build all components:
+
+  make
+
+You will find in ./output/images/ the following files:
+  - rootfs.cpio
+  - rootfs.cpio.gz
+  - rootfs.tar
+  - zImage
+
+The generated zImage does include the rootfs.
+
+Boot the PDK board
+==================
+
+The i.MX31 PDK contains a RedBoot bootloader in flash, which can be used to
+boot the newly created Buildroot images from the network.
+
+This necessitates to setup a TFTP server first. This setup is explained for
+example in Freescale i.MX31 PDK 1.5 Linux User's Guide [4].
+
+Here is a sample RedBoot configuration, for proper network boot of Buildroot on
+the i.MX31 PDK:
+
+    RedBoot> fconfig -l
+    Run script at boot: true
+    Boot script:
+    .. load -r -b 0x100000 zImage
+    .. exec -c "console=ttymxc0,115200"
+
+    Boot script timeout (1000ms resolution): 2
+    Use BOOTP for network configuration: false
+    Gateway IP address: <your gateway IP address>
+    Local IP address: <your PDK IP address>
+    Local IP address mask: 255.255.255.0
+    Default server IP address: <your TFTP server IP address>
+    Board specifics: 0
+    Console baud rate: 115200
+    Set eth0 network hardware address [MAC]: false
+    GDB connection port: 9000
+    Force console for special debug messages: false
+    Network debug at boot time: false
+
+Adapt those settings to your network configuration by replacing the appropriate
+network addresses where necessary.
+
+You might want to verify that your i.MX31 PDK switches settings are the correct
+ones for UART, power, boot mode, etc. Here is a reference switches
+configuration:
+
+    SW4
+    1   2   3   4   5   6   7  8
+    ON off off off off off off ON
+
+    SW5 SW6 SW7 SW8 SW9 SW10
+     0   1   0   0   0    0
+
+See the i.MX31 PDK Linux Quick Start Guide [5] for more details on the switches
+settings.
+
+Connect a serial terminal set to 115200n8 and power on the i.MX31 PDK board.
+Buildroot will present a login prompt on the serial port.
+
+Enjoy!

-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").

+Subject: [PATCH] imximage: Remove failure when no IVT offset is found
+
+Sometimes imximage throws the following error:
+
+  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
+  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
+  MKIMAGE u-boot-dtb.imx
+Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp
+arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed
+
+Later on, when running mkimage for the u-boot.imx it will succeed in
+finding the IVT offset.
+
+Looks like some race condition happening during parallel build when
+processing mkimage for u-boot-dtb.imx and u-boot.imx.
+
+A proper fix still needs to be implemented, but as a workaround let's
+remove the error when the IVT offset is not found.
+
+It is useful to have such message, especially during bring-up phase,
+but the build error that it causes is severe, so better avoid the
+build error for now.
+
+The error checking can be re-implemented later when we have a proper
+fix.

-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
-  - imx-boot-imx8mqevk-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
-stoping 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!
