This is a prerequisite for the sl28 board support which needs at least
kernel 5.7, thus pack it into one series. This is a new patch and thus,
there is no former version. This patch can also be picked early, before the
other two patches.

Changes since v4:
 none

Changes since v3:
 new patch

  To: buildroot

In linux, newer architectures like ARM64 and RISC-V keep their device
tree sources organized by subdirectories. When these device trees are
installed by the kernel they will keep the directory names. But
buildroot strips the prefixes when installing them into /boot or the
images directory.
Sometimes the bootloader references the device tree by name (e.g.
u-boot has the environment variable 'fdtfile') which also includes
the prefix directory.
Make it possible to keep this prefix during installation, so we can
be compatible with other distributions and make it easier for the
user, because he doesn't have to change that environment variable.

Hi,

formerly, this was a seperate patch. But because the sl28 board also needs
another patch now, I combined all of them into one patch series. So
actually, there is no v2, nor a v3 of this patch.

Changes since v4:
 make the Makefile expression more readable, thanks Yann

Changes since v3:
 none

Changes since v2:
 none

Now that upstream supports this board add buildroot support for it, too.

This supports:
 - latest upstream linux kernel. Since the support for this board and
   its SoC is still in active development, we want to follow the
   upstream kernel releases for now.
 - building an image which can be installed to eMMC, SD card or USB
   thumb drive.
 - upstream u-boot patches are pending, therefore no support for
   building a bootloader for now.

Changes since v4:
 none

Changes since v3:
 - removed custom kernel version, instead use the latest 5.7 kernel

Changes since v2:
 - added udev rules 71-smarc-networking.rules, to rename the network
   interfaces according to the SMARC specification.
 - removed arm-smmu.disable_bypass=n kernel paramter, since the real fix is
   now upstream and will be included in 5.7
 - use full path in PARTUUID="$($HOST_DIR/bin/uuidgen)" to be sure we are
   using our own uuidgen
 - mention fdtfile in readme.txt
 - fixed typo in readme.txt
 - mention non-working network with vendor's bootloader in readme.txt
 - set BR2_KERNEL_DTB_KEEP_DIRNAME=y

Changes since v1:
 - added readme.txt
 - changed from u-boot boot script to extlinux.conf booting
 - enable eudev and added udev rules to properly name network interfaces
 - removed CONFIG_FSL_ENETC_HW_TIMESTAMPING=y
 - added CONFIG_NET_SCH_CBS, CONFIG_NET_SCH_ETF, CONFIG_NET_SCH_TAPRIO,
   CONFIG_FSL_ENETC_QOS and iproute2, as this it the main feature of this
   board
 - added var2 device tree
 - generate PARTUUID in post-build.sh to be able to use the resulting image
   on any block device which the board supports for booting
 - (keep post-build.sh for consistency reasons)

+Kontron SMARC-sAL28
+===================
+
+How to build it
+===============
+
+Configure Buildroot:
+
+  $ make kontron_smarc_sal28_defconfig
+
+Change settings to fit your needs (optional):
+
+  $ make menuconfig
+
+Compile everything and build the rootfs image:
+
+  $ make
+
+Copying the image to a storage device
+=====================================
+
+Buildroot builds an image which can be written to the internal eMMC
+storage, a SD card or an USB thumb drive. You can use the following
+command on your host:
+
+  $ sudo dd if=output/images/sdcard-emmc.img of=/dev/sdx bs=1M
+
+Where /dev/sdx is the corresponding block device of your SD card or USB
+thumb drive. To flash it on your internal eMMC use the following command on
+the board:
+
+  # dd if=sdcard-emmc.img of=/dev/mmcblk1 bs=1M
+
+Be sure you have not booted from the internal eMMC in this case!
+
+Booting the board
+=================
+
+By default the bootloader will search for the first valid image, starting
+with the internal eMMC. Consult the vendor documentation on how to use the
+DIP switches to select specific boot devices. To use the bootloader
+environment set the boot_targets correspondingly. E.g.:
+
+  # setenv boot_targets usb0
+
+To boot from an USB thumb drive.
+
+The device tree is loaded according to the filename in fdtfile. The
+following command will set the default device tree, which works on almost
+all variants (with less features of course):
+
+  # setenv fdtfile freescale/fsl-ls1028a-kontron-sl28.dtb
+
+Set this to a device tree which fits your board variant.
+
+Connect your serial cable to SER1 and open your favorite terminal emulation
+program (baudrate 115200, 8n1). E.g.:
+
+  $ picocom -b 115200 /dev/ttyUSB0
+
+You will get a warning reported by fdisk when you examine the SD card.
+This is because the genimage.cfg file doesn't specify the SD card size
+(as people will naturally have different sized cards), so the
+secondary GPT header is placed after the rootfs rather than at the end
+of the disk where it is expected to be.
+
+You will see something like this at boot time:
+
+[    4.552797] GPT:Primary header thinks Alt. header is not at the end of the disk.
+[    4.560237] GPT:266272 != 7864319
+[    4.563565] GPT:Alternate GPT header not at the end of the disk.
+[    4.569596] GPT:266272 != 7864319
+[    4.572925] GPT: Use GNU Parted to correct GPT errors.
+
+What does not work
+==================
+
+For reasons unknown, the network card doesn't work if you use the original
+vendor bootloader. Board support patches for upstream u-boot are currently
+pending. Stay tuned.

This config option should be:
BR2_LINUX_KERNEL_DTB_KEEP_DIRNAME

This was changed due to a naming-scheme mismatch

Thanks. I've applied your patch, with some minor changes.

Changed the commit title to follow the format:

	configs/foo_defconfig: new defconfig

> +BR2_KERNEL_DTB_KEEP_DIRNAME=y

I fixed the name of this option, as pointed by Heiko.

I dropped this, as we want our defconfigs to be minimal.

Thanks!

Thomas
