[PATCH v2 0/1] meson: Demonstration of using binman to produce the image

[Simon Glass]

The Odroid-C2 is quite a complicated image with many steps. It is an ideal
example for how Binman can be used.

Add a binman description and update the instructions accordingly.

[PATCH v2 1/1] RFC: Move Odroid-C2 to use binman to produce the image

[Simon Glass]

This shows how binman can be used to replace the long and complicated
instructions with an automated build. It is still complicated to read
but users don't have to worry about the details.

It needs some tidying up and only supports Odroid-C2 at present.

+
+If you copy the `$UBOOTDIR/odroid-c4/fip/g12a/aml_encrypt_g12a` tool somewhere
+in your path, you can omit the `BINMAN_TOOLPATHS` option. The `BINMAN_INDIRS`
+variable provides a space-seperated list of directories containing the various
+binary blobs needed by the build.
+
+To see these, look at the Binman image description in
+`arch/arm/dts/meson-sm1-odroid-c4-u-boot.dtsi`.

This says C2 and only supports C2, but you're modifying th C4
documentation?  I'm just a random distro maintainer with interest in
this and want to be clear is all.

Like the v1, the work is really nice, but the dependency on vendor binary-only
tools doesn't make feel confident about merging this.

We have open source implementation for all boards, but still dependeing on
tools we must manually build isn't optimal.

What would be optimal would be to re-implement those tools into python
libraries and merge them into the u-boot tree then use them from binman.

But this could be merged as first step, them the python libaray could be
modified to support the binary tools & a probable python re-implementation.

So long as we can download it from somewhere, that is OK, or at least
better than nothing. Is there a standard download location for the
tools?

Or C, perhaps? Then binman can call the tools.

Yes I think it would good to get this in, even if it only supports a
few boards. It is easy to add more, when possible.

The tools are Linux x86-64 only, so...

There's no "official" location, historically the tools was shipped with the
buildroot fork in the u-boot sources, but it has been moved into different
repos now they do not ship buildroot anymore, and we can only find those tools
on the SBC vendor u-boot sources.

And the tools have the same name but only support different SoCs, there's no
versioning, licence nor documentation... so relying on those tools is a nightmare.

This is why we made a central repository with the tools + binaries for
each board with an easy script to generate the bootable binary:
https://github.com/LibreELEC/amlogic-boot-fip
and documented at:
https://u-boot.readthedocs.io/en/latest/board/amlogic/pre-generated-fip.html

Yes, but the open source tools aren't heavily maintained, have different ABIs...

Supporting GXBB and GXL/G12A is impossible, the binary format is totally different
for example so we should import 2 different tools.

If this can rely on the amlogic-boot-fip repo, then why not, then we can find
a native solution to replace calling those tools.

You say Odroid-C2, but the patches seem to address the Odroid-C4...

There are currently four different signing recipes that depend on the
board family that you are building for:

- GXBB
- GXL/GXM
- G12A/SM1
- G12B

The G12A/SM1 and G12B recipes are identical except for a different
signing binary used. The latest Amlogic boards (S905X4, T7, etc.)
also have incremental changes, but none are currently supported in
Linux or u-boot.

One of the challenges for binman will be the signing tools. Currently
this patchset depends upon Amlogic binaries. Apart from them being
closed-source and thus undesirable, they are also x86_64 only and
there are quite a few users (and at least one major distro) needing
to build on arm64 hardware.

There is an open-source tool called gxlimg which supports GXL and newer
boards. IMHO it would make a lot of sense for u-boot to absorb the
functionality of gxlimg (and extend support backwards to GXBB) as this
would remove the dependency on Amlogic binaries and allow u-boot build
and binman signing to be done anywhere.

https://github.com/repk/gxlimg

> The patch is for testing by Christian, who I hope can help get this landed for all the Amlogic boards.

I will try to find the time to test this, but it’s not something I
could do more with (as only supporting 1/4 of the board families
that I need to build for, bu I do appreciate it’s a POC).

In case you’re not aware, Makefile based signing is implemented in
the amlogic-boot-fip repo that I’m currently tooled around:

https://github.com/LibreELEC/amlogic-boot-fip 

This is the “competition” so to speak. It’s quite simple and widely
used by most of the Amlogic supporting distros right now.

Fair enough, but another option would be to allow 'binman tool -f
gxlimg' to work, which should be easy. Then we can make use of the
existing C code, using binary tools for the unsupported ones.

Yes, it's a start.

Well at least that provides the recipes.

gxlimg also does not have the full featureset of the Amlogic signer.
The most important to me being lz4 compression.
I'm still trying to get support from Amlogic for open source ATF at
least for GXX but that has numerous hurdles to overcome and more
hurdles for future designs.

The issue with the boot fips is that they control too many things (CPU
freq, DDR freq, M3 control code, and more) to make it universal.

That's fine, but it doesn't need to be open source for binman to use it.

OK.

So I wonder how best to move this forward so that we can build things
using binman and everything works?
