Since kernel 5.13, the SATA issue can be reproduced again following the SATA node move from L3 bus to L4_cfg in commit 8af15365a368 ("ARM: dts: Configure interconnect target module for dra7 sata"). Fix it by adding an empty dma-ranges property to l4_cfg and segment@100000 nodes (parent device tree node of SATA controller) to inherit the 2GB dma ranges limit from l3 bus node. Note: A similar fix was applied for PCIe controller by commit 90d4d3f4ea45 ("ARM: dts: dra7: Fix bus_dma_limit for PCIe"). Fixes: 8af15365a368 ("ARM: dts: Configure interconnect target module for dra7 sata").
