Until recently, generation of a bootloader for the Avnet
Zedboard (and in general all Xilinx Zynq based boards)
has required to use the development tools by Xilinx
(Vivado, XSDK) and to walk through a quite painful
procedure to generate the First Stage Boot Loader
(FSBL) and the bootable BOOT.BIN image.
This commit makes Buildroot independent on the Xilinx
flow by utilizing U-Boot SPL and booting the Zynq's
PL by U-Boot.
The FSBL generation is not a problem anymore with U-Boot
2015.07 where a generic ps7_init.c file is included and
used to build the U-Boot SPL for various boards including
Zedboard. The ps7_init.c file has been released under
GNU/GPL license for this purpose. For details, see
http://lists.denx.de/pipermail/u-boot/2015-April/210664.html
To create the BOOT.BIN automatically, there is a script
zynq-boot-bin.py in the Xilinx github repository. This
script is not included in the upstream of U-Boot so
I attach it as a series of patchs (0001-0003) generated
against U-Boot 2015.07.
There is a little catch, the U-Boot 2015.07 is not released
yet, so this commit is based on 2015.07-rc2. However, as
soon as it is out, the download site of U-Boot can be
redirected to the release archive instead of fetching it
by git.
The last patch (0004) creates a Zedboard+Buildroot specific
U-Boot environment to boot smoothly from SD card. It tries
to load a file system.bit into the Zynq's PL (only if it
exists). It is also possible to alter the booting by an
uEnv.txt file located on your SD card. The uEnv.txt is
a plain text file with <key>=<value> pairs one per line.
Steps to create a working Buildroot for Zedboard:
a) use U-Boot 2015.07 (done by this commit)
b) patch it to use zynq-boot-bin.py (done by this commit)
--------------------------
1) make zedboard_defconfig
2) make UBOOT_BIN=u-boot-dtb.img
3) copy files boot.bin, u-boot-dtb.img, rootfs.cpio.uboot,
uImage, zynq-zed.dtb into your SD card
4) boot your Zedboard
Note that I redefine variable UBOOT_BIN to u-boot-dtb.img
(instead of u-boot.img) to be installed in to the images/
directory. This binary works for the generated SPL:
U-Boot SPL 2015.07-rc2 (Jun 18 2015 - 16:42:58)
mmc boot
reading system.dtb
spl_load_image_fat_os: error reading image system.dtb, err - -1
reading u-boot-dtb.img
reading u-boot-dtb.img
U-Boot 2015.07-rc2 (Jun 18 2015 - 16:42:58 +0200)
Model: Zynq ZED Board
I2C: ready
DRAM: ECC disabled 512 MiB
MMC: zynq_sdhci: 0
Using default environment

Zedboard information including schematics, reference designs, and manuals are

-The U-Boot firmware for the Xilinx Zynq All Programmable SoC depends
-on some proprietary code. This dependency consists of a pair of
-files are available from the Xilinx SDK installation.
-
-You will need these files from Xilinx SDK installation to generate
-the U-Boot firmware:
- ps7_init.c
- ps7_init.h
-
Buildroot will create the following files and place them in the
+$ make UBOOT_BIN=u-boot-dtb.img
<output>/images directory.
zynq-zed.dtb
rootfs.cpio.uboot
uImage
- u-boot.img
+ u-boot-dtb.img
boot.bin
-
-uboot.bin -- U-Boot SPL w/ Xilinx boot.bin wrapper
----------------------------------------------------
-
-Due to licensing issues, the files ps7_init.c/h are not able to be
-distributed with the U-Boot source code. These files are required to make a
-boot.bin file.
-
-If you already have the Xilinx tools installed, the following sequence will
-unpack, patch and build the rfs, kernel, uboot, and uboot-spl.
-
-make zedboard_defconfig
-make uboot-patch
-cp ${XILINX}/ISE_DS/EDK/sw/lib/hwplatform_templates/zed_hw_platform/ps7_init.{c,h} \
-output/build/uboot-xilinx-v2014.1/board/xilinx/zynq/
-
-After copying these files into the U-Boot source tree, you can
-continue the build with:
-
-make
-
-*Notice*
-While the build will successfully complete without the ps7_init.*
-files, the uboot.bin file generated by this configuration will not
-function properly on the Zedboard. Therefore, it is imperative that
-the ps7_init.* files be copied into the U-Boot source tree any time
-the clean, or uboot-dirclean targets are made.
-
+The SPL searchs for u-boot-dtb.img so it is desirable to redefine
+the UBOOT_BIN variable as it was done in the example above.
Resulting system
----------------
A FAT32 partition should be created at the beginning of the SD Card
and the following files should be installed:
/boot.bin
- /devicetree.dtb
+ /zynq-zed.dtb
/uImage
- /uramdisk.image.gz
- /u-boot.img
+ /rootfs-cpio.uboot
+ /u-boot-dtb.img
All needed files can be taken from output/images/
-boot.bin, uImage and u-boot.img are direct copies of the same files
+boot.bin, uImage and u-boot-dtb.img are direct copies of the same files
available on output/images/
-devicetree.dtb is just zynq-zed.dtb renamed.
+The attachedpatchs of U-Boot enables to create boot.bin file
+automatically without the need of Xilinx tools. The U-Boot's
+environment is redefined there to work with Buildroot out-of-the-box.
+
+You can alter the booting procedure by creating a file uEnv.txt
+in the root of the SD card. It is a plain text file in format
+<key>=<value> one per line:
-uramdisk.image.gz is rootfs.cpio.uboot renamed

It is a bit annoying to have this script as patches. Will it be merged
in the upstream U-Boot at some point? If yes, then having it as patches
is OK. Otherwise, I'd prefer to have a separate host-zync-boot-script
package, which simply downloads and installs this script in
$(HOST_DIR), and then only the patch changing the U-Boot Makefile to
call this script.

Yes, this is OK.

This should just go to board/avnet/zedboard/readme.txt, no need to have
it in the commit log if you're updating that readme file.

Dear Thomas,
thank you for the review. I've made the changes accordingly.
I've created host-zynq-boot-bin package to cover the small
python script. It downloads U-Boot xilinx-v2015.1 from Xilinx
github for this purpose (quite an overkill, isn't it...).
There are now just 2 patches of U-Boot 2015.07. 0001 adds
calling of the zynq-boot-bin.py and 0002 fixes the default
U-Boot environment to boot out-of-the-box from SD card.
There is still one thing to solve (I wasn't sure how).
There is no dependency specified between U-Boot and the
host-zynq-boot-bin package. It should be probably conditional
but what kind of condition to write there? Should we use
it for every Zynq architecture? (Is it possible to detect
it by Buildroot?)
Regards
Jan Viktorin

The purpose of this package is to provide a small
Python script zynq-boot-bin.py to Buildroot. The
script creates a BOOT.BIN file from U-Boot's SPL
to boot Xilinx Zynq without needing the Xilinx FSBL.

From: Jan Viktorin <viktorin@rehivetech.com>
Until recently, generation of a bootloader for the Avnet
Zedboard (and in general all Xilinx Zynq based boards)
has required to use the development tools by Xilinx
(Vivado, XSDK) and to walk through a quite painful
procedure to generate the First Stage Boot Loader
(FSBL) and the bootable BOOT.BIN image.
This commit makes Buildroot independent on the Xilinx
flow by utilizing U-Boot SPL and booting the Zynq's
PL by U-Boot.
The FSBL generation is not a problem anymore with U-Boot
2015.07 where a generic ps7_init.c file is included and
used to build the U-Boot SPL for various boards including
Zedboard. The ps7_init.c file has been released under
GNU/GPL license for this purpose. For details, see
http://lists.denx.de/pipermail/u-boot/2015-April/210664.html
To create the BOOT.BIN automatically, there is a script
zynq-boot-bin.py in the Xilinx github repository. This
script is installed by host-zynq-boot-bin package.
The attached patch (0001) fixes U-Boot environment to use it.
There is a little catch, the U-Boot 2015.07 is not released
yet, so this commit is based on 2015.07-rc2. However, as
soon as it is out, the download site of U-Boot can be
redirected to the release archive instead of fetching it
by git.
The last patch (0002) creates a Zedboard+Buildroot specific
U-Boot environment to boot smoothly from SD card. It tries
to load a file system.bit into the Zynq's PL (only if it
exists). It is also possible to alter the booting by an
uEnv.txt file located on your SD card. The uEnv.txt is
a plain text file with <key>=<value> pairs one per line.

You can revert the two packages: make host-zynq-boot-bin depend on uboot, and
move the call to the python script to the host-zynq-boot-bin package. One less
patch for uboot :-)

So, you mean to drop the patch 0001 and call the zynq-boot-bin.py from
BUILD/INSTALL (?) stage of this package? (I expect the dependency on
uboot will guarantee, it is called after uboot.) The package will get
the path to the uboot's build dir as UBOOT_DIR, is it right?
So host-zynq-boot-bin should depend on uboot and it is up to the user
to select this package to create the boot.bin file automatically
or not. Is that OK?

Yes, from the BUILD stage.
You'll want to set _INSTALL_STAGING = NO and _INSTALL_IMAGES = YES.

Yep.

It will, but we prefer not to rely on that. Since uboot.mk will anyway install
the spl.bin file to $(IMAGES_DIR), you can take it from there.

Exactly!

Hello,
based on the previous discussions, here are the changes
of the host-zynq-boot-bin which is now calling the zynq-boot-bin.py
script during its HOST_BUILD stage to create a boot.bin image
from the U-Boot's SPL. The host-zynq-boot-bin uses the variable
BR2_TARGET_UBOOT_SPL_NAME to determine the name of the installed
SPL binary.
I've added dependency on host-python, however, I am not sure
whether it is correct this way. It works for me.
There is only one patch for U-Boot attached that creates
an environment that boots out-of-the-box on Zedboard.
Regards
Jan Viktorin

The package creates file images/boot.bin to boot
Xilinx Zynq based boards. It might not work with
U-Boot older then 2015.07.
The script zynq-boot-bin.py is contained in the
Xilinx repository of U-Boot (it is not in upstream).

To: buildroot
From: Jan Viktorin <viktorin@rehivetech.com>
Until recently, generation of a bootloader for the Avnet
Zedboard (and in general all Xilinx Zynq based boards)
has required to use the development tools by Xilinx
(Vivado, XSDK) and to walk through a quite painful
procedure to generate the First Stage Boot Loader
(FSBL) and the bootable BOOT.BIN image.
This commit makes Buildroot independent on the Xilinx
flow by utilizing U-Boot SPL and booting the Zynq's
PL by U-Boot.
The FSBL generation is not a problem anymore with U-Boot
2015.07 where a generic ps7_init.c file is included and
used to build the U-Boot SPL for various boards including
Zedboard. The ps7_init.c file has been released under
GNU/GPL license for this purpose. For details, see
http://lists.denx.de/pipermail/u-boot/2015-April/210664.html
To create the boot.bin automatically, the host-zynq-boot-bin
package is required to be set (done in zedboard_defconfig).
The U-Boot 2015.07 is not released at the moment, so this
commit is based on 2015.07-rc2. However, as soon as it is
out, the download site of U-Boot can be redirected to the
release archive instead of fetching it by git.
The attached patch (0001) creates a Zedboard+Buildroot specific
U-Boot environment to boot smoothly from SD card. It tries
to load a file system.bit into the Zynq's PL (only if it
exists). It is also possible to alter the booting by an
uEnv.txt file located on your SD card. The uEnv.txt is
a plain text file with <key>=<value> pairs one per line.

+4) boot your Zedboard
+
+Note that I redefine variable UBOOT_BIN to u-boot-dtb.img
+(instead of u-boot.img) to be installed in to the images/
+directory. This binary works for the generated SPL:
+

A FAT32 partition should be created at the beginning of the SD Card
and the following files should be installed:
/boot.bin
- /devicetree.dtb
+ /zynq-zed.dtb
/uImage
- /uramdisk.image.gz
- /u-boot.img

Python (2.6 or 2.7) is already a required package for Buildroot
(http://nightly.buildroot.org/manual.html#requirement-mandatory).

Since we only need a single file from this archive, perhaps it is better to
set (untested):
ZYNQ_BOOT_BIN_SOURCE = zynq-boot-bin.py
ZYNQ_BOOT_BIN_SITE = https://raw.githubusercontent.com/Xilinx/u-boot-xlnx/$(ZYNQ_BOOT_BIN_VERSION)/tools

As mentioned by Baruch, host-python dependency shouldn't be needed.

It's actually _NEEDS_HOST_PYTHON, so this is clearly not needed.

Hello,
thanks to Baruch and Arnout for comments. I think this the final
version. The host-zynq-boot-bin now downloads just the python script
(thank you for this tip, I was looking for such solution).
The second commit is unchanged.

Until recently, generation of a bootloader for the Avnet
Zedboard (and in general all Xilinx Zynq based boards)
has required to use the development tools by Xilinx
(Vivado, XSDK) and to walk through a quite painful
procedure to generate the First Stage Boot Loader
(FSBL) and the bootable BOOT.BIN image.
This commit makes Buildroot independent on the Xilinx
flow by utilizing U-Boot SPL and booting the Zynq's
PL by U-Boot.
The FSBL generation is not a problem anymore with U-Boot
2015.07 where a generic ps7_init.c file is included and
used to build the U-Boot SPL for various boards including
Zedboard. The ps7_init.c file has been released under
GNU/GPL license for this purpose. For details, see
http://lists.denx.de/pipermail/u-boot/2015-April/210664.html
To create the BOOT.BIN automatically, the host-zynq-boot-bin
package is required. It automatically creates the boot.bin.
The U-Boot 2015.07 is not released at the moment, so this
commit is based on 2015.07-rc2. However, as soon as it is
out, the download site of U-Boot can be redirected to the
release archive instead of fetching it by git.
The attached patch (0001) creates a Zedboard+Buildroot specific
U-Boot environment to boot smoothly from SD card. It tries
to load a file system.bit into the Zynq's PL (only if it
exists). It is also possible to alter the booting by an
uEnv.txt file located on your SD card. The uEnv.txt is
a plain text file with <key>=<value> pairs one per line.

-uboot.bin -- U-Boot SPL w/ Xilinx boot.bin wrapper
----------------------------------------------------
-
-Due to licensing issues, the files ps7_init.c/h are not able to be
-distributed with the U-Boot source code. These files are required to make a
-boot.bin file.
-
-If you already have the Xilinx tools installed, the following sequence will
-unpack, patch and build the rfs, kernel, uboot, and uboot-spl.
-
-make zedboard_defconfig
-make uboot-patch
-cp ${XILINX}/ISE_DS/EDK/sw/lib/hwplatform_templates/zed_hw_platform/ps7_init.{c,h} \
-output/build/uboot-xilinx-v2014.1/board/xilinx/zynq/
-
-After copying these files into the U-Boot source tree, you can
-continue the build with:
-
-make
-
-*Notice*
-While the build will successfully complete without the ps7_init.*
-files, the uboot.bin file generated by this configuration will not
-function properly on the Zedboard. Therefore, it is imperative that
-the ps7_init.* files be copied into the U-Boot source tree any time
-the clean, or uboot-dirclean targets are made.
-
+Steps to create a working Buildroot for Zedboard:
+
+a) use U-Boot 2015.07 (is set by zedboard_defconfig)
+b) install host-zynq-boot-bin (done automatically by dependency system)
+--------------------------
+1) make zedboard_defconfig
+2) make UBOOT_BIN=u-boot-dtb.img
+3) copy files boot.bin, u-boot-dtb.img, rootfs.cpio.uboot,
+ uImage, zynq-zed.dtb into your SD card
+4) boot your Zedboard
+
+Note that I redefine variable UBOOT_BIN to u-boot-dtb.img
+(instead of u-boot.img) to be installed in to the images/
+directory. This binary works for the generated SPL:
+
+ U-Boot SPL 2015.07-rc2 (Jun 18 2015 - 16:42:58)
+ mmc boot
+ reading system.dtb
+ spl_load_image_fat_os: error reading image system.dtb, err - -1
+ reading u-boot-dtb.img
+ reading u-boot-dtb.img
+
+ U-Boot 2015.07-rc2 (Jun 18 2015 - 16:42:58 +0200)

+ I2C: ready
+ DRAM: ECC disabled 512 MiB
+ MMC: zynq_sdhci: 0
+ Using default environment
+ ...
Resulting system
----------------
A FAT32 partition should be created at the beginning of the SD Card
and the following files should be installed:
/boot.bin
- /devicetree.dtb
+ /zynq-zed.dtb
/uImage
- /uramdisk.image.gz
- /u-boot.img
+ /rootfs-cpio.uboot
+ /u-boot-dtb.img
All needed files can be taken from output/images/
-boot.bin, uImage and u-boot.img are direct copies of the same files
+boot.bin, uImage and u-boot-dtb.img are direct copies of the same files

Since this is a host-only package, you need not specify either;

- both are anyway only valid for target packages.

Although what you wrote does work, it is not absolutely correct: the
build commands should just really build, not install anything in the
output directories.
You should generate the files in the package build directory, and
provide a command that does the install (even if it is just copying the
generated files).
> +$(eval $(host-generic-package))
But, then since you install in $(BINARIES_DIR), which is definitely not
what we usually do for host packages. The expected output of a host
package is to install something in $(HOST_DIR), so that it can later be
used (e.g. by another package, or by a post-build/post-image script)
Here's what I think should be done:
ZYNQ_BOOT_BIN_VERSION = xilinx-v2015.1
ZYNQ_BOOT_BIN_SOURCE = zynq-boot-bin.py
ZYNQ_BOOT_BIN_SITE = https://raw.githubusercontent.com/Xilinx/u-boot-xlnx/$(ZYNQ_BOOT_BIN_VERSION)/tools
ZYNQ_BOOT_BIN_LICENSE = GPLv3+
# No license file, license in file itself
HOST_ZYNQ_BOOT_BIN_DEPENDENCIES = host-python
define HOST_ZYNQ_BOOT_BIN_INSTALL_CMDS
@cp $(DL_DIR)/$(ZYNQ_BOOT_BIN_SOURCE) \
$(HOST_DIR)/usr/bin/$(ZYNQ_BOOT_BIN_SOURCE)
endef
$(eval $(hhost-generic-package))
And then in the board README file, state something along the lines:
---8<---
To finalise the boot device, run the following command:
$ ./output/host/usr/bin/zynq-boot-bin.py \
-u output/images/boot.bin \
-o /path/to/the/boot-stuff
---8<---
(you get the idea)
Note: that's what we do for the Raspberry Pi, for example, where we
install the 'mkknlimg' utility in $(HOST_DIR) and tell the user how to
use it in the board readme file:
---8<---
The kernel image must be marked with a special header so that the
bootloader of the RaspberryPi knows it supports Device Tree:
$ ./output/host/usr/bin/mkknlimg output/images/zImage \
/mnt/mountpointboot/zImage
---8<---

Well, we need to review and test them...
We currently have 401 patches pending in our patch queue:
https://patchwork.ozlabs.org/project/buildroot/list/
Since there's not many of us doing reviews/tests, it takes time.
If you want to increase the likelyhood your patches are reviewed soon
(and I've already started), you can help reduce the patch queue:
- get a patch (not yours), apply it to your Buildroot tree, build a
configuration with that patch and test it (as much as you can, at
least build-test in various target configurations: arm, mips...
LE/BE, glibc/uClibc/musl, internal/external toolchain...) and report
your findings to the list
- get a patch (not yours), look at it, and see if it fits in the
Buildroot 'spirit' (code style, mandatory information, licensing...)
and report to hte list.
See:
http://buildroot.net/downloads/manual/manual.html#_contributing_to_buildroot
http://buildroot.net/downloads/manual/manual.html#_reviewing_and_testing_patches

Yann E. MORIN.

But actually, it's not a host package, it's a target package. Took me some time
to realize that however :-) See below.

Actually, no, we actually require a system-python to exist. I think it also
needs to be python2 though we don't check for that. And to be honest, I have no
idea why we require it...
But I certainly wouldn't like to have to build a host-python just to be able to
build the boot loader... So I'm glad there's no dependency on host-python.

That's what Jan originally had, but I told him to do it this way :-)
You can view zynq-boot-bin as something which really should be part of uboot.
The only point of this "program" is to create the bootloader. It will never be
applied on anything except the bootloader. It doesn't need any additional
configuration or command line arguments. So it would be quite pointless to burde
the user with writing that stuff in a post-build script.
Perhaps, however, it should go into the boot/ directory instead of packages. It
is, after all, a pre-bootloader, like at91bootstrap.

I think the same approach could be taken there. Though I can't say I understand
much of all the hoops you have to jump through to boot an RPi.

I don't know why we require it for packages, but we at least need it for
the manual.
I was added way back in 2010 byy Thomas P. to fix #1531.

Right, that would be a better location.
Still, I believe we should handle this tool as a host tool, to support
users that build their bootloader outside of Buildroot (we already
install similar tools for this reason).

I respectfully disagree. ;-)
rpi-firmware installs a utility to add a header (really, a trailler) to
the kernel image. Since the user can build his kernel outside Buildroot,
we still want to leave him/her the possibility to tag the kernel
properly; hence we install this utility in $(HOST_DIR), either when
doing the SDcard manually, or from a post-image script.
I believe we are here in a similar situation with host-zynq-boot-bin.
However, we might be a bit more helpful here, so we have a way to
automatically run those commands in a sane, generic way, like we have
with TARGET_FINALIZE_HOOKS for target-finalize, but this time for
images.
Note: we might _technically_ be able tore-use TARGET_FINALIZE_HOOKS,
but I'm a bit uneasy to hijack it to deal with images, when it was meant
to deal with the content of $(TARGET_DIR).

Well, it's pretty similar to the zedboard case (from what I see in the
zedboard readme):
- a first partition, FAT16 or FAT32, with a bunch of files in there:

* [Buildroot] [PATCH v3 1/2] host-zynq-boot-bin: new package

Hello Arnout, Yann,
I am glad you are interested in this little feature. My original
goal was to deliver a simple out-of-the-box mechanism to easily
create a bootable system for Zedboard without any additional
steps and with the ability to turn it off easily if necessary.
I do not understand, how should this script be treated as
a bootloader stuff. I see it just as a helper host tool like the
uboot-tools are (a common host package). However, uboot-tools
is integrated quite deeply, it creates uImage (done by Kernel
build-system) and especially root file-system (done by Buildroot).
I would expect that zynq-boot-bin.py works in a similar way.
I have no clue about the TARGET_FINALIZE_HOOKS but it sounds
promising.
What I find quite a good idea is to use a post-<something>
script. But for that purpose, I thinks a working script in
the boards/avnet/zedboard exactly for this purpose should be
provided together with a preset inside the zedboard_defconfig
to use it as default. This creates an out-of-the-box working
configuration that is easily customizable. But what about other
Zynq-based boards (well, there is no one there at the moment,
but...)? Could they share the same script?
Another point that was omitted here (but it is described in the
readme.txt) is that the SPL searchs for uboot-dtb.img while booting.
This file is however not installed in the images directory. Instead,
user gets the u-boot.img that does not work together with the SPL
(at least for me). This is confusing... First, I do not get the working
SPL automatically, second, I do not get the right U-Boot image. From
this point of view, I'd like the original patch-based implementation :).
Is this also an issue for other boards?
I am about to:
* remove the _INSTALL_STAGING, _INSTALL_IMAGES settings,
* specify the license,
* put there the EXTRACT_CMDS to avoid failure when trying to extract
the zynq-boot-bin.py as an tar archive (is this correct assumption?)
* put there the INSTALL_CMDS to install the zynq-boot-bin.py into
HOST_DIR
The last step is not clear to me. I also found a kind of inspiration in
fs/cpio:
34 $(BINARIES_DIR)/rootfs.cpio.uboot: $(BINARIES_DIR)/rootfs.cpio host-uboot-tools
35 $(MKIMAGE) -A $(MKIMAGE_ARCH) -T ramdisk \
36 -C none -d $<$(ROOTFS_CPIO_COMPRESS_EXT) $@
Would it be possible to define similar rules in uboot.mk?
$(BINARIES_DIR)/boot.bin: host-zynq-boot-bin
python2 $(HOST_DIR)/usr/bin/zynq-boot-bin.py \
-u $(@D)/spl/u-boot-spl.bin -o $@
Regards,
Jan

Hello Yann,
I see your point. I was just uncertain whether it was forgotten
or if there is some issue I did not see. Now, I see you are doing very
well, apologize. Recently, I've beated the contribution process (not
as easy as it looks like when just passively watching the mailing list),
probably I will beat also the review process after some time.

After reading the discussion with Arnout and Yann, here is what I'd
personally prefer to see for this:
* A host-zynq-boot-bin package, which only downloads and installs the
Python script to $(HOST_DIR)/usr/bin. If the script is Python 2 only
then you must make it depend on host-python, because the system
Python can be either Python 2 or 3. If however, the script is Python
2 and Python 3 compatible, there is no need to add a host-python
dependency, because we can use the system provided Python
interpreter.
* One of the two following solutions:
- An extension of the U-Boot Config.in + uboot.mk to optionally
generated a Zynq image. It would add host-zynq-boot-bin in the
dependencies of U-Boot, and call the Python script at the right
time. Something along the lines of:
ifeq ($(BR2_TARGET_UBOOT_ZYNQ_IMAGE),y)
define UBOOT_GENERATE_ZYNQ_IMAGE
$(HOST_DIR)/usr/bin/python2 $(HOST_DIR)/usr/bin/zynq-..py -o $(BINARIES_DIR)/...
endef
UBOOT_DEPENDENCIES += host-zynq-boot-bin
UBOOT_POST_INSTALL_IMAGES_HOOKS += UBOOT_GENERATE_ZYNQ_IMAGE
endif
- Just not do anything special in U-Boot, and add an entry in
menuconfig to enable the host-zynq-boot-bin package, and in your
board configuration, write a post-build script that generates the
final image.

Hello all,
here follows another version of the patch series. I have rewritten it
based on the previous discussion with Yann, Arnout and Thomas.
The patch 1 is unrelated, I did not know whether to post it alone
or if it is OK to put it here...
The host-zynq-boot-bin is just "download & install" now.
I've added a new output format of U-Boot to generate u-boot-dtb.img which
is booted by the SPL. The generation of the BOOT.BIN file is moved into
uboot.mk as suggested by Thomas. I am little bit unsure about the config
BR2_TARGET_UBOOT_ZYNQ_IMAGE (the depends on/select). To enable the BOOT.BIN
generation, the user must set the dtb.img format and enable SPL. However,
the zedboard_defconfig does it so it might be OK.
The zedboard related changes are slightly modified but almost the same.
Regards
Jan Viktorin

Allow to generate u-boot-dtb.img. This is the same format
as u-boot.img, however, it contains a built-in device-tree.
This file is being loaded by the U-Boot SPL.

The package provides a Python script that can create
the file BOOT.BIN to boot Xilinx Zynq based boards.
The script zynq-boot-bin.py is contained in the
Xilinx repository of U-Boot (it is not in upstream).

The U-Boot v2015.07 builds working SPL without a manual
intervention. The BOOT.BIN is generated from the standard
SPL so no BR2_TARGET_UBOOT_SPL_NAME redefinition is needed.
The SPL requires the u-boot-dtb.img file to boot properly.

This commit integrates generation of a bootable image
for Xilinx Zynq. The generation is independent on Xilinx
flow and utilizes the host-zynq-boot-bin package. The only
required step is to generate a proper U-Boot SPL (instead
of the FSBL).
The SPL generation might work when providing the working
ps7_init.c file to U-Boot. However, from U-Boot 2015.07
a set of generic ps7_init.c files is included and used to
build the U-Boot SPL for various boards. The ps7_init.c file
has been released under GNU/GPL license for this purpose.
For details, see
http://lists.denx.de/pipermail/u-boot/2015-April/210664.html
The SPL searchs for u-boot-dtb.img when booting so we
enforce using of the BR2_TARGET_UBOOT_FORMAT_DTB_IMG format.

This patch changes the U-Boot's default environment to
boot Zedboard out-of-the-box from SD card.
The sdboot procedure tries to load a file system.bit into
the Zynq's PL (only if it exists). It is also possible to
alter the booting by an uEnv.txt file located on your SD card.
The uEnv.txt is a plain text file with <key>=<value> pairs
one per line.

I agree with your patch, but I would prefer dtb_img entry to be before IMG.
I know that the file is not properly organized but that's not a reason
to worsen it.
Other than that (which could be fixed when merged) it's fine by me.

I've done quite a few changes:
[Thomas:
- remove appearance of the package in menuconfig, U-Boot will depend
on it directly, so there's no need for it to appear in menuconfig
- use $(INSTALL) instead of cp for the installation
- remove @ before the extract and install commands.]
and applied the patch. Thanks!

I've made one change:
[Thomas: remove select of BR2_PACKAGE_HOST_ZYNQ_BOOT_BIN, since this
option no longer exists.]
and applied the patch. Thanks!
