...in other words the normal bootstrap loaer code as used with other
NAND boting systems, too.

I'm sorry, but I cannot understand this argument. Because the code is
so small you cannot put it into the U-Boot tree? That makes no sense
to me.

To code used for NAND booting for example on PPC 4xx systems has size
limitations, too, but we keep this all in nand_spl/

Maybe you could merge your code into this common infrastructure, too?
Please feel free to discuss details with the NAND custodian.

Why do you need a special compiler?

No, that would be definitely the wrong place.
