Subject: [PATCH V2 09/21] RISC-V: smpboot: Create wrapper smp_setup()
Date:   Thu, 16 Feb 2023 23:50:31 +0530
Message-Id: <20230216182043.1946553-10-sunilvl@ventanamicro.com>

smp_setup() currently assumes DT-based platforms. To enable ACPI,
first make this a wrapper function and move existing code to
a separate DT-specific function.
