From 1c55d62fb9ccc107cb4fefa9bb04cb16395ca84c Mon Sep 17 00:00:00 2001 From: Chanho Park Date: Fri, 18 Aug 2023 14:11:03 +0900 Subject: riscv: cpu: make riscv_cpu_probe to EVT_DM_POST_INIT_R callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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) Thus, we need to move riscv_cpu_probe function in order to register the timer earlier than initr_dm_devices.
