From: Peter Barada Date: Tue, 13 Nov 2012 07:40:28 +0000 (+0000) Subject: Pass sdrc timing values through board_sdrc_timings structure X-Git-Tag: v2013.01-rc3~9^2~1^2~15 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=8c4445d26633f43fcd04add3d6cdc3bc41d14841;p=oweals%2Fu-boot.git 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.
