I don't know how to determine CFG_ENV_ADDR. Why does it add 0x0F0000 or 0x070000?
You must come up with a sector map of your flash device(s) and define which sector(s) to use for the U-Boot environment. In this case the offset of the used sector chages depending on the size of the used flash chips - it's always 0x10000 = 64 kB from the end.
Another question is If I save u-boot in NOR flash, can my kernel boot from NAND? or should I save u-boot in NAND?
Yes, you can. No, you should not.
