From: Marek Vasut Date: Sat, 1 Aug 2015 19:35:18 +0000 (+0200) Subject: ddr: altera: sdram: Introduce socfpga_sdram_get_config() X-Git-Tag: v2015.10-rc2~194 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5af914189ec73b2241ba79950f98849fddaf32a2;p=oweals%2Fu-boot.git ddr: altera: sdram: Introduce socfpga_sdram_get_config() Introduce socfpga_sdram_get_config() function implement in a board file, which returns the socfpga_sdram_config structure. This is the last step in cleaning up the socfpga_mmr_init_full(), but not the last step which allows removing the inclusion of sdram.h from drivers/ddr/altera/sdram.c thus far.
