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. As suggested by Simon[3], we can address this by adding EVT_DM_POST_INIT_R event and it's spy-callback function. Changes from v1: - Add EVT_DM_POST_INIT_R event type and emit it after relocation - Make riscv_cpu_probe as the callback of EVT_DM_POST_INIT_R [1]: https://lists.denx.de/pipermail/u-boot/2023-June/521220.html [2]: https://www.qemu.org/docs/master/system/riscv/sifive_u.html#running-u-boot [3]: https://lore.kernel.org/u-boot/capnjgz2pbhvy_wlvq7xcd-hykkwoh8r3lgxfoo7s6sbvj0+...@mail.gmail.com/ Chanho Park (2): dm: event: add EVT_DM_POST_INIT_R event type riscv: cpu: make riscv_cpu_probe to EVT_DM_POST_INIT_R callback arch/riscv/cpu/cpu.c | 11 +++-------- drivers/core/root.c | 6 ++++-- include/event.h | 1 + 3 files changed, 8 insertions(+), 10 deletions(-) -- 2.39.2
