From 10c14261f3c0644d2ae21785701f5aa3898d98e9 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 2 Aug 2015 19:00:23 +0200 Subject: ddr: altera: sequencer: Wrap IO_* macros Introduce structure socfpga_sdram_io_config to wrap the IO configuration values in board file. Introduce socfpga_get_sdram_io_config() function, which returns this the structure. This is another step toward wrapping the nasty QTS generated macros in board files and reducing the pollution of the namespace.
