If I understood you right, U-Boot is maybe not the best choice for me, because there are only 2KB XIP Flash available at address 0x00000000 on startup.
I wouldn't put it like that. IMO your hardware is not the best choice for you because it is missing a proper boot ROM (256 kB flash would be just perfect) to allow you using a decent boot loader without jumping in loops.
I 100% agree that dealing with a separate NOR boot ROM is so much more easier. However, I also see booting from NAND data flash with a small boot readable sector is quickly becoming popular in lower cost/smaller footprint/less power consumption equipment.
IMHO instead of denying this reality, perhaps we (as U-Boot developers/users) should make some enhancements to deal with this situation in a formal supported way before too many forks occur.
After all it is supposed to be **Universal** boot loader. ;)
