Reserved memory regions can be used for more than just DMA regions, so only enabling on DMA_DECLARE_COHERENT (via HAS_DMA) or DMA_CMA is wrong. This effectively doesn't matter except for the few cases arches select NO_DMA. At least, these users of RESERVEDMEM_OF_DECLARE depend on reserved memory support: arch/riscv/mm/init.c:RESERVEDMEM_OF_DECLARE(elfcorehdr, "linux,elfcorehdr", elfcore_hdr_setup); drivers/memory/tegra/tegra210-emc-table.c:RESERVEDMEM_OF_DECLARE(tegra210_emc_table, "nvidia,tegra210-emc-table", drivers/soc/fsl/qbman/bman_ccsr.c:RESERVEDMEM_OF_DECLARE(bman_fbpr, "fsl,bman-fbpr", bman_fbpr); drivers/soc/fsl/qbman/qman_ccsr.c:RESERVEDMEM_OF_DECLARE(qman_fqd, "fsl,qman-fqd", qman_fqd); drivers/soc/fsl/qbman/qman_ccsr.c:RESERVEDMEM_OF_DECLARE(qman_pfdr, "fsl,qman-pfdr", qman_pfdr); Let's simplify things and enable OF_RESERVED_MEM when OF_EARLY_FLATTREE is enabled.
