So far, Stefan's NAND boot > code managed to do pretty well in this respect. This is a bad example. The 4k NAND bootloader (in nand_spl/*) doesn't do any serial output at all. It's really like the here described first stage bootloader. Just setup the CPU as much as needed, setup the SDRAM (in a limited way - you can't support this I2C SPD probing in the 4k) and load the "real" U-Boot from NAND into SDRAM and start it. The first serial output is from the "real" U-Boot and not from the NAND loader.
