RFC: Add rimage and tomlc99 to Zephyr's west manifest

[teburd]

Origin

rimage hosted by thesofproject
tomlc99 hosted by the sofproject

tomlc99 in this case is a clone of https://github.com/cktan/tomlc99

Purpose

Adds metadata, cryptographic signing, and other elf manipulations for the purpose of the sof project firmware. Used with west sign by default when building for intel adsp targets.

Mode of integration

Integrate as a module

Maintainership

Description

rimage is required to be used when build a loadable firmware image for Intel ADSP platforms. Each platform has a configuration file in toml stored in the rimage repository along with a signing key for cryptographic signing.

The tool, configurations live today in the rimage repository. Currently the rimage repository is not cloned with west update. This makes building loadable firmware images error prone as
rimage and the configurations for each platform may change over time.

It would add immense convenience and allow one less external step if rimage were cloned, built, and had its configuration files readily available through west.

Dependencies

rimage depends on openssl and tomlc99

tomlc99 is available as a git submodule as part of the rimage git repository

Is the plan for this to be added to the zephyr manifest disabled by default with a group filter, and have the sof manifest enable that group by default?

this will be enabled by default, it is an SOF dependency. We do not have visibility or control over the SOF manifest itself.

@nashif 's suggestion to move rimage.git back into SOF.git:

• [FEATURE] remove SOF build time dependency to rimage headers thesofproject/sof#8178

[marc-hb]

rimage transfer to sof.git submitted in:

• Transfer rimage git history to subdirectory tools/rimage/ in the sof git repo thesofproject/sof#8297
