arm: rmobile: Add Silicon Linux EK874 board support The EK874 development kit from Silicon Linux is made of CAT874 (the main board) and CAT875 (the sub board that goes on top of CAT874). This patch adds the required board support to boot Si-Linux EK874 board based on R8A774C0 SoC. DTS files apart from r8a774c0-ek874-u-boot.dts and r8a774c0-u-boot.dtsi have been imported from Linux kernel 5.11 commit f40ddce88593 ("Linux 5.11").

ARM: dts: rmobile: Fix RPC-IF device node names According to the Generic Names Recommendation in the Devicetree Specification Release v0.3, and the DT Bindings for the Renesas Reduced Pin Count Interface, the node name for a Renesas RPC-IF device should be "spi". Especially on R-Car Gen3 and RZ/G2, the node name matters, as the node is enabled by passing a DT fragment from TF-A to U-Boot, and from U-Boot to subsequent software. Fix this by renaming the device nodes from "rpc" to "spi". Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

renesas: Fix RPC-IF compatible values The compatible values used for device nodes representing Renesas Reduced Pin Count Interfaces were based on preliminary versions of the Device Tree Bindings. Correct them in both DTSi files and drivers, to match the final DT Bindings. Note that there are no DT bindings for RPC-IF on RZ/A1 yet, hence the most logical SoC-specific value is used, without specifying a family-specific value.
