Subject: [PATCH] RISC-V: Don't print details of CPUs disabled in DT
Date: Tue, 14 Oct 2025 22:00:09 +0530	[thread overview]
Message-ID: <20251014163009.182381-1-apatel@ventanamicro.com> (raw)

Early boot stages may disable CPU DT nodes for unavailable
CPUs based on SKU, pinstraps, eFuse, etc. Currently, the
riscv_early_of_processor_hartid() prints details of a CPU
if it is disabled in DT which has no value and gives a
false impression to the users that there some issue with
the CPU.

Fixes: e3d794d555cd ("riscv: treat cpu devicetree nodes without status as enabled")
