There are several new subdirs altera/ dfl/ lattice/ xilinx/ Each subdir has a Kconfig that has a new/reused if FPGA_BLA ... existing configs ... endif FPGA_BLA Which is sourced into the main fpga/Kconfig Each subdir has a Makefile whose transversal is controlled in the fpga/Makefile by obj-$(CONFIG_FPGA_BLA) += bla/ This is the dfl/ subdir part. Create a dfl/ subdir Move dfl-* files to it. Add a Kconfig and Makefile Because FPGA_DFL is now used in dfl/Kconfig in a if/endif block, all the other configs in dfl/Kconfig implicitly depend on FPGA_DFL. So the explicit dependence can be removed. Also since FPGA_DFL depends on HAS_IOMEM, it can be removed from the other configs.
