qemu-system-m68k has introduced in v6.0 a new pure virtual machine
that is now supported by linux v5.19.

The goal of this series is to provide petitboot as an embedded bootloader
for it (like it is for the IBM spapr machine).

The first patch introduces petitboot package, the second patch the
configuration to build buildroot with petitboot for the QEMU machine.

You can test it with:

  qemu-system-m68k -M virt -kernel images/vmlinux \
                   -initrd images/rootfs.cpio.xz \
                   -append "console=ttyGF0" --nographic

v7:
  - set BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_5_19=y
  - fix errors reported by check-package
  - add gitlab testing (Cédric)
  - update boot-qemu-image.py to support petitboot

v6:
  - rebase

v5:
  - remove BR2_CCACHE_DIR, BR2_PACKAGE_DTC and BR2_PACKAGE_DTC_PROGRAMS

v4:
  - address Thomas' comments
  - remove petitboot-mtd config as libflash is not available

v3: v2: v1:
  - first version, I messed up with list subscription and git-publish...

Petitboot doesn't start a shell but a GUI.
Manage the menu to switch to the shell.
Use "poweroff -f" as we don't have init

Enable the test for qemu_m68K_virt.
