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.
