Allow platforms to reuse DT headers and dtsi includes directly form upstream DT subtree which will be frequently synced with Linux kernel. This will further allow us to drop corresponding DT includes copy from U-Boot tree. Also, since the DT includes from upstream DT subtree are done after DT includes from U-Boot tree, so it shouldn't cause any conflicts. Tested-by: Bryan Brattlof <[email protected]> Signed-off-by: Sumit Garg <[email protected]> --- Changes in v6: - None Changes in v5: - None Changes in v4: - New patch to reuse upstream DT includes by U-Boot as per Brian's use-case for TI K3 SoCs.
