I stripped down u-boot code to 96k (just to fit in the very first NAND page, so
I don't care about NAND Errors (samsung told me that...)) and it has:
serial support, nand support (ecc), mmc support with vfat support. that's it. No fancy
LCD support, ethernet, or whatever. I think it is enough for a bootloader. 
It loads kernel from nand into ram, and jumps into it.
All other init stuff is done at the kernel driver level, so I see no problem here...

So don't re-invent the wheel...
