arm: socfpga: Add DT support for SoCFPGA and add socfpga_socrates target This patch includes the latest DT sources for socfpga from the current Linux kernel. And enables CONFIG_OF_CONTROL for the new build target "socfpga_socrates" (the EBV SoCrates board) to make use of this new DT support. Until this patch, the only SoCFPGA U-Boot target in mainline is "socfpga_cyclone5". This build target is not (yet) changed to support DT. So nothing changes for this target. Even though the long-term goal should be to move all SoCFPGA targets over to DT. One of the reasons to enable DT support in SoCFPGA is, that I need to support multiple different SPI controllers for this platform. This is the QSPI Cadence controller and the Designware SPI master controller. Both are implemented in the SoCFPGA. And enabling both controllers is only possible by using the new driver model (DM). The DM SPI code only supports DT based probing. So it was easier to move SoCFPGA to DT than to add the (deprecated) platform-data based probing to the DM SPI suport. Note that the image with the dtb embedded is u-boot-dtb.img. This needs to be used now for those DT enabled boards instead of u-boot.img.

arm: socfpga: dts: Move to SPDX license identifiers The socfpga dts files are copied from the Rocketboards.org repository. In U-Boot we usually replace the full-blown license header text with the SPDX license identifiers. Lets do this for these new dts files as well. I just forgot to do this while adding the DT support for socfpga.

arm: socfpga: Do not enable gmac1 in Cyclone V dtsi The GMAC which is enabled is purely board property, so do not enable arbitrary GMAC in DT include files. Same goes for PHY mode, which is again a board property. The CycloneV SoCDK does this correctly, but SoCrates doesn't. This bug never manifested itself though, since all the boards ever used the GMAC1 . This bug manifests itself only on boards that utilise GMAC0. Signed-off-by: Marek Vasut <marex@denx.de>

arm: socfpga: Make the DT mmc node consistent The socfpga_cyclone5.dtsi has an mmc0 node, socrates has mmc node. This makes aliases not very usable, so make everything into mmc0. Moreover, zap the useless mmc alias while at this. Signed-off-by: Marek Vasut <marex@denx.de>
