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. ;)

Best regards,
