Subject: [PATCH v4 03/11] ARM: dts: socfpga: add Mercury+ AA1 for u-boot dts

Introduce u-boot specific device-tree files for Enclustra Mercury+ AA1 SoMs (Intel/arria10).

Generic device-tree fragments for linux and U-boot shall be provided in dts/upstream. The selection of the generic device-tree fragments depends on a selected boot-mode and a selected carrier board.

On Intel/Arria10 a handoff setup is needed for initialization of various clock / pinmux / DRAM settings only used by U-Boot provided by the current patch.

The RAW read implementation in fs_loader is not upstream yet, I afraid this might not working, you want help to upstream?
