Hello,
Here is a patch set that adds basic support for the Marvell Armada 370
and Armada XP SOCs. For now, the support is quite minimal, since only
the serial port is supported. However, a significant part of the work
has been the development of the tools that allow to extract/create
bootable images and to push a bootable image through the UART to the
hardware platform.
I expect to work on adding support for more devices (such as the
network interface) and possibly to add support for the older, but
popular, Marvell Kirkwood SoC family. Contributions are of course
welcome.
Changes since v2:
- Use $(srctree) when accessing kwbimage.cfg from arch/arm/Makefile,
in order to allow out-of-tree builds to work properly. Noticed by
Grégory Clement.
- Improve the error message displayed by kwbimage when the DDR3
training blob cannot be found. Since it must first be extracted by
the user, it is a good idea to guide him. Suggested by Grégory
Clement.
- Change the file name of the binary blobs for each board, in order
to make it different for each board. So instead of being 'binary.0'
it is know 'globalscale-mirabox-binary.0', etc. This allows to keep
multiple binary blobs for different boards around at the same time.
Changes since v1:
- Drop the patch fixing scripts/checkpatch.pl since it has been
merged upstream.
- Improve kwbimage to add options that allow to override the payload
filename, the boot media, the destination address and execution
address from the command line. Suggested by Sascha Hauer.
- Add an integration of kwbimage to the Barebox build process. Now,
when an ARCH_MVEBU platform is selected, a barebox.kwb file is
automatically generated using the board kwbimage.cfg, and a
barebox.kwbuart is generated using the board kwbimage.cfg + an
override of the boot media to be UART.
- Simplify the kwbimage.cfg to no longer contain the payload filename
(it is passed by Barebox using kwbimage -p option), the destination
and execution addresses (those are passed by Barebox using kwbimage
-d and -e options, which allows to ensure they match
CONFIG_TEXT_BASE).
- Change the default boot media of the kwbimage.cfg to be the real
boot media used on the platform, typically SPI or NAND. Since an
image for UART is always automatically generated by overriding the
boot media, it makes sense to have the real boot media in
kwbimage.cfg.
- Remove incorrect whitespace change in scripts/Makefile. Noticed by
Sascha Hauer.
In detail, the patch set contains:
* A kwbimage tool. This tool allows to extract existing bootloader
images, and create new bootloader images. It is more or less
similar in purpose to the kwbimage tool from U-Boot, but is capable
of handling 'version 1' images used by Armada 370/XP, and not only
allows to create images, but also extract images.
A typical usage is to first extract an existing bootloader image:
./scripts/kwbimage -x -i <existing-image> -o <some-directory>
As an output, you typically get 3 files: kwbimage.cfg (a text file
that describes the configuration of the image in a format
ressembling the one used by U-Boot), binary.0 (the binary blob that
does the DDR3 training) and payload (the bootloader itself).
Being able to extract an image is needed in order to get the DDR3
training code, and re-use it with Barebox.
An image is then later created with:
./scripts/kwbimage -c -i <path/to/kwbimage.cfg> -o <image>
For each board, the kwbimage.cfg file is typically located in
arch/arm/boards/<board-name>/. The DDR3 training code must however
be extracted from an existing bootloader image of your board,
usually the one provided by the board manufacturer.
* A kwboot tool to push a bootloader through UART. It is directly
taken from U-Boot source code, to which I've added some fixes:
- Extend the timeouts, to actually make it work on Armada
370/XP. This has originally been found by Willy Tarreau.
- Ignore non-Xmodem characters, so that the original DDR3 training
code can be used without modifications (Willy had to change it to
make it output its messages on a different serial port, otherwise
it was confusing the Xmodem implementation)
- Output to stdout all the non-Xmodem characters so that if
something goes wrong during the transfer, we have some
informations. It also shows the messages output by the DDR3
training code.
- Remove the 'patch' feature that patches an image to have the UART
type. This requires a knowledge of the header format, which is
different between version 0 (kirkwood) and version 1 (armada
370/xp). It is not really needed anyway since kwbimage can
extract and create images.
* The SoC-level code, which for now only consists in a minimal
clocksource driver, a function to register an UART, a fixed-rate
clock, and a function that determines the amount of RAM by looking
at the SDRAM windows registers.
* An integration of kwbimage generation. When an ARCH_MVEBU platform
is selected, both barebox.kwb and barebox.kwbuart images are
generated automatically.
* The board-level code for the Armada 370 Mirabox from Globalscale,
the Armada XP OpenBlocks AX3 from Plathome and the Armada XP GP
from Marvell.

Thomas

The Marvell EBU SoCs (Kirkwood, Armada 370, Armada XP) have a BootROM
that understand a specific image format, composed of a main header,
several extension headers and a paylod. This image can be booted from
NAND, SPI, SATA, UART, NOR, etc.
This patch adds a tool that allows to extract the components and
configuration of existing images, and to create new images.

This tool is used with Marvell EBU SoC to trigger the UART boot mode
provided by the SoC BootROM, and push the bootloader image to the
target using the Xmodem protocol.
It has been taken from the U-Boot source code, with minor
modifications to make it work with Armada 370/XP platforms.

When a ARCH_MVEBU platform is selected, generate barebox.kwb and
barebox.kwbuart images from barebox.bin, using kwbimage.
barebox.kwb is generated by executing kwbimage on the board
kwbimage.cfg file, and is therefore designed to be booted from the
default boot media of the board, as defined by kwbimage.cfg (typically
a NAND flash or SPI flash).
barebox.kwbuart is generated by executing kwbimage on the board
kwbimage.cfg file, but by overriding the boot media to be UART. This
image is suitable for usage with the kwbtool and is generally useful
for recovery purposes.

Could you add a note which revision of u-boot it was pulled from? That
should make later syncs between the two versions much easier.
To that end, Sascha, do you think it is worth the extra commit to have
one commit copying the file over, and a second adding changes to make it
work with Armada 370/XP?
thx,
Jason.

From a user point of view everything is OK now. You can add my
Tested-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
for the whole series except the last patch, because I didn't tested yet
on the Armada XP GP platform but I would be very surprise that it doesn't
work for this platform.

The revision the tool originally came from should be enough I think.
Anyway, if Thomas is willing to split this into two patches I'll take
that version instead.

Applied all.
Regarding the commit id from which the kwboot tool has been taken from I
decided to ignore it since the tool hasn't been changed in U-Boot since
the original commit adding it.

There is a problem with this series: It doesn't build without the
addtional binary needed for the kwb tool. Can we make creating a kwb
image optional so that we are able to build the defconfigs without
additional dependencies?

Hum, right. So we should make the default build target to not build
barebox.{kwb,kwbuart} and only make barebox.bin?
Or there should be a config option somewhere to say "I also want
the .{kwb,kwbuart} images generated" ?
Neither of those are ideal, because most likely people will not notice
the possibility of building the .{kwb,kwbuart} images, but I understand
the concern of not being able to build defconfigs.
Tell me which solution you prefer, and I'll send a patch that
implements it.
Thanks!

How about a warning like:
"Warning: 'plathome-openblocks-ax3-binary.0' does not exist. Not building barebox.kwb"
Also not an ideal solution, but I think there is no really good way to
solve this other than including the binary in the tree which probably
has some licensing issues.

The problem is that the Makefile doesn't know that kwbimage will need
plathome-openblocks-ax3-binary.0, it would have to parse the
kwbimage.cfg file to know about this.
Also, not all .kwb images will require this binary blob. Kirkwood and
Dove do not require such a binary blob, and a kwb image can be built
with just the kwbimage.cfg and barebox.bin. So it is really a
per-kwbimage.cfg knowledge.
Another solution is to add an option to kwbimage that allows it to list
which files are needed to make the build succeed. Then
arch/arm/Makefile can call this, check that we have the needed files.
If not, it shows a warning, otherwise it goes on with the build.
Other ideas welcome, of course.
Best regards,
Thomas
