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.
Since this patch was applied, I see a warning message WARNING: no status info for 'socfpga_socrates' WARNING: no maintainers for 'socfpga_socrates' when I run tools/genboardscfg.py
I think you should add the maintainership info F: configs/socfpga_socrates_defconfig to somewhere of MAINTAINERS to suppress the warning message.
Yes, should be done. Not sure where I should add such information though. We don't have a board directory for this socrates board (yet). And the toplevel MAINTAINERS file seems to be reserved for the custodian entries.
Any ideas / suggestions welcome.
It looks like this socfpga_socrates board borrows most of the parts from socfpga_cyclone board, so I think you can append your maintainership info to board/altera/socfpga/MAINTAINERS.
Perhaps it might be helpful to refer to board/sunxi/MAINTAINERS. The core support of SUNXI boards are owned by Hans de Goede and some additional files are maintained by other people.
