Enable ppc64le qemu

[shenki]

I'd like to enable boot tests for the ppc64le toolchains. buildroot master has support for a qemu_ppc64le_pseries machine as of 9d5b5b7bfb1d8cd3c12067650a8d2bf1c877a422.

Here's a change that enables the configuration:

https://github.com/shenki/toolchains-builder/tree/enable-ppc64le

However I think we need to wait until the toolchains-builder uses a newer release of buildroot?

I'm happy to write and test patches with some guidance as to what needs to be done. Thanks!

Thanks for this contribution, very useful!

No, we don't necessarily need to wait until toolchains-builder uses a newer release of Buildroot. toolchains-builder uses a Buildroot fork at https://github.com/free-electrons/buildroot-toolchains, with one branch for the stable toolchains and one branch for the bleeding edge toolchains. And those branches containing some backports/fixes, and therefore we can backport your ppc64le defconfig patch into those branches.

Sorry for the slow reply. Since your commit, I've changed build.sh quite significantly, but I've adapted your change. I've also done some changes to board/qemu/ppc64le-pseries/readme.txt to make the Qemu command line more similar to the one in board/qemu/ppc64-pseries/readme.txt, and I've fired up a test build at https://gitlab.com/free-electrons/toolchains-builder/pipelines/18271434. We'll see what it gives. If it works fine, I'll apply, and submit the necessary patches to upstream Buildroot.

Thanks, fixed as of commit d572850d9457a45314e395bca5bf5360458a294b !
