Also added a few helper functions for DDR1 & DDR2 to print SPD info and verify the checksum.

Hi Kumar,
There is a "do_sdram" command in common/cmd_i2c.c that I believe is doing the same thing, but probably a lot less (I suspect the command is showing its age).
#if defined(CONFIG_CMD_SDRAM) U_BOOT_CMD( isdram, 2, 1, do_sdram, "isdram - print SDRAM configuration information\n", "chip\n - print SDRAM configuration information\n" " (valid chip values 50..57)\n" ); #endif
Are you aware of that command? Is your SPD dump going to supersede it?
Best regards, gvb
