From 8c4445d26633f43fcd04add3d6cdc3bc41d14841 Mon Sep 17 00:00:00 2001 From: Peter Barada Date: Tue, 13 Nov 2012 07:40:28 +0000 Subject: Pass sdrc timing values through board_sdrc_timings structure Instead of passing individual registers by value to board_get_mem_timings, pass a board_mem_timings structure pointer for the board files to fill in. Pass same structure pointer to write_sdrc_timings. This saves about 90 bytes of space in SPL.
