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.
