Are you sure you're executing this code in spd_sdram():

#ifdef CFG_DDR_SDRAM_CLK_CNTL	/* Optional platform specific value */
	ddr->sdram_clk_cntl = CFG_DDR_SDRAM_CLK_CNTL;
#else


What I don't understand is that we can

I really don't know at this point.  I've never seen this problem, and tftp isn't 
particularly demanding, so I don't understand what's happening.  My only guess is that 
your memory is not configured exactly right, so some memory operations work and some 
don't.  Since I'm not expert on DDR, I really can't say what the problem is.  Sorry.
