Subject: [PATCH V5 10/21] RISC-V: smpboot: Create wrapper setup_smp()
Date:   Mon,  8 May 2023 17:22:26 +0530
Message-Id: <20230508115237.216337-11-sunilvl@ventanamicro.com>
In-Reply-To: <20230508115237.216337-1-sunilvl@ventanamicro.com>

Precedence: bulk

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