Subject: [PATCH v2 1/4] RISC-V: Add RISC-V specific arch_match_cpu_phys_id
Date:   Wed, 10 Apr 2019 16:04:40 -0700
Message-Id: <20190410230443.15729-2-atish.patra@wdc.com>

OF/DT core has a hook for architecture specific logical cpuid to hartid
mapping. By implementing this, we can pass the logical cpu id to cpu
node parsing functions.
