In Labgrid there is the concept of a 'role', which is similar to the U-Boot board ID in U-Boot's pytest subsystem.
The role indicates both the target and information about the U-Boot build to use. It can also provide any amount of other configuration. The information is obtained using the 'labgrid-client query' operation.
Make use of this in tests, so that only the role is required in gitlab and other situations. The board type and other things can be queried as needed.
Use a new 'u-boot-test-getrole' script to obtain the requested information.
With this it is possible to run lab tests in gitlab with just a single 'ROLE' variable for each board.

I'm a little confused here. Why can't we construct "role" from board_type+board_identity and then we have the board conf.${board_type}_${board_identity} file set whatever needs setting to be "labgrid" ?
The role is equivalent to the board identity, not the combination of the U-Boot board type and the board identity. I went this way to avoid having to type long and complicated roles when connecting to boards. It is similar to how things work today, except that the board type is implied by the 'role'.
For boards which have multiple identities (e.g. can support two different board types), Labgrid handles acquiring and releasing the shares resources, to avoid any problems.
I guess I have two sets of questions. First, if it's basically the board identity why can't we just use that as the role name, in your setup?
Yes, that's what I am doing. If you look in console.labgrid you can see that it is passing U_BOOT_BOARD_IDENTITY as the -r argument.
But second, I'm not sure why we need this. The labgrid support we worked up here (but, sigh, it's not really clean enough to post) has: $ cat bin/lootbox/conf.rpi_4_na console_impl=labgrid reset_impl=labgrid flash_impl=labgrid.rpi_4 flash_writer=labgrid.rpi_4
For example and: $ cat bin/writer.labgrid.rpi_4 set -e
build=${U_BOOT_BUILD_DIR}
$LG_CLIENT write-files -T ${build}/u-boot.bin kernel8.img
So I don't know what the "role" part you have is for. And yes, there end up being multiple writer.labgrid.FOO scripts because for TI K3 platforms (such as beagleplay) we have: $ cat bin/writer.labgrid.ti-k3 set -e build=${U_BOOT_BUILD_DIR}
if [ -z "${tispl}" -o -z "${uboot}" -o -z "${tiboot3}" ]; then echo "Must configure tispl, uboot, tiboot3 and optionally sysfw" echo "per the board documentation." exit 1 fi echo "Writing build at ${build}" $LG_CLIENT write-files -T ${build}/${tispl} tispl.bin $LG_CLIENT write-files -T ${build}/${uboot} u-boot.img $LG_CLIENT write-files -T ${build/_a??/_r5}/${tiboot3} tiboot3.bin echo "Done writing build"
In all cases we first build U-Boot and then pass the build directory to test.py, in something like: export LG_PLACE=rpi4 ./test/py/test.py -ra --bd rpi_4 --build-dir .../build-rpi4 \ --results-dir .../results-rpi4 --persistent-data-dir .../pd-rpi4 \ --exitfirst
The only U-Boot side changes I needed to make were for counting the SPL banner instances, and that was regardless of framework (a particularly fun platform will show it 3 times).
Yes it is possible to build U-Boot separately. Of course that involved various blobs and so on, so every board is different. The approach I have taken here is to have Labgrid call buildman to build what is needed, with the blobs defined in the environment.
You can use the -B flag to use a pre-built U-Boot, with the scripts I've included.
