Since the Patch 55171aedda88, VisionFive2 booting has been broken [1]. VisionFive2 board requires to enable CONFIG_TIMER_EARLY but booting went to panic from initr_dm_devices due to lack of a timer device.
- Error logs initcall sequence 00000000fffd8d38 failed at call 00000000402185e4 (err=-19)
We can reproduce it on Qemu Sifive HiFive Unleashed emulation[2] after enabling CONFIG_TIMER_EARLY manually.
