For downlink hw accelerated traffic request to consume SRAM memory for hw forwarding descriptors queue. Moreover, in some configurations QDMA blocks require a contiguous block of system memory for hwfd buffers queue. Introduce the capability to allocate hw buffers forwarding queue via the reserved-memory DTS property instead of running dmam_alloc_coherent(). v2: https://lore.kernel.org/r/20250509-airopha-desc-sram-v2-0-9dc3d8076dfb@kernel.org v1: https://lore.kernel.org/r/20250507-airopha-desc-sram-v1-0-d42037431bfa@kernel.org ==================== Link: https://patch.msgid.link/20250521-airopha-desc-sram-v3-0-a6e9b085b4f0@kernel.org Signed-off-by: Paolo Abeni --- 31eaaa5cb5e3a11290e037dbe00c90eb9f48b78a
