m68k: virt: Switch to qemu-virt-ctrl driver

2026-04-13T10:16:10+00:00

Register the "qemu-virt-ctrl" platform device during board initialization to utilize the new generic power/reset driver. Consequently, remove the legacy reset and power-off implementations specific to the virt machine. The platform's mach_reset callback is updated to call do_kernel_restart(), bridging the legacy m68k reboot path to the generic kernel restart handler framework for this machine. To prevent any regressions in reboot or power-off functionality when the driver is not built-in, explicitly select POWER_RESET and POWER_RESET_QEMU_VIRT_CTRL for the VIRT machine in Kconfig.machine.
