Subject: [PATCH 01/13] arm: mem_init: use memblock_phys_free() to free DMA memory on SA1111
Date: Thu,  6 Mar 2025 20:51:11 +0200	[thread overview]
Message-ID: <20250306185124.3147510-2-rppt@kernel.org> (raw)
In-Reply-To: <20250306185124.3147510-1-rppt@kernel.org>

From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>

This will help to pull out memblock_free_all() to generic code.
