configs/qemu_ppc64le_powernv8: new defconfig PowerNV is the platform using the OPAL [1] firmware on OpenPOWER systems. OPAL first loads a kernel and an initramfs image based on buildroot including a second boot loader petitboot [2]. The latter does device discovery and kexecs a new Linux image from disk or network. QEMU implements PowerNV machines [3] for the POWER8, POWER9 and Power10 processors which are used for dev and tests. POWER8 images being compatible with POWER9 and Power10, simply add a single qemu_ppc64le_powernv8 board for all. The QEMU script boots directly from a nvme disk because it is simple enough but a real system would boot from a ramfs first.

configs/qemu_ppc64*: bump to binutils-2.38 Commit 1e2fe860f3a2 (configs/qemu_ppc64*: downgrade binutils to 2.36.1). Since then, we've dropped support for binutios 2.36, and hte default is 2.38.x, which has the required changes to fix: https://github.com/linuxppc/issues/issues/388 Pin the qemu-ppc64 defconfig to explicitly use binutils 2.38.x Signed-off-by: Cédric Le Goater <clg@kaod.org> [yann.morin.1998@free.fr: - explictily force binutils 2.38 - reword commit log to explain why - reword commit log: it's not really a revert ] Signed-off-by: Yann E.
