Re: [U-Boot-Users] [PATCH] Fix memory initialization on MPC8349ITX

The instability persists. I had debugging on, and the debug line in spd_sdram.c still prints this value as 0x00000000.

Well, that's odd. 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.
