On the Renesas RZ/Five SoC by default we want to configure 128MiB of memory ranging from 0x58000000 as a non-cacheable + bufferable region in the PMA and populate this region as PMA reserve DT node with shared DMA pool and no-map flags set so that Linux drivers requesting any DMA'able memory go through this region. PMA node passed to the above stack: reserved-memory { #address-cells = <2>; #size-cells = <2>; ranges; pma_resv0@58000000 { compatible = "shared-dma-pool"; reg = <0x0 0x58000000 0x0 0x08000000>; no-map; linux,dma-default; }; }; Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com> Reviewed-by: Yu Chien Peter Lin <peterlin@andestech.com> Reviewed-by: Anup Patel <anup@brainfault.org>
