I just got a revision 3.1 board here that, when I follow those steps (don't define CFG_DDR_SDRAM_CLK_CNTL and don't set sdram_clk_cntl to 0), it works when before it didn't. So I'm wondering if we should do both: 1. Set CFG_DDR_SDRAM_CLK_CNTL in MPC8349ITX.h 2. Change spd_sdram() to not write 0 if CFG_DDR_SDRAM_CLK_CNTL is not set. I just don't understand why some boards have the right value on power-up and some don't, and why some boards work okay with 0 and others don't. -- Timur Tabi Linux Kernel Developer @ Freescale
