This stuff does not belong in the NAND driver; it belongs under your board or cpu directory.
I have tried to move those 'usb_boot' to board files. the only problem is I have to run this 'usb_boot' very early. after CPU load the real u-boot to memory the usb_boot will not working. I will try to found more info about this. then explain more in next email.
OK, so you need to run it during the SPL phase -- but there should be some board/cpu-specific file for the SPL (if not, create one).
Current examples of this include nand_spl/board/freescale/p1_p2_rdb/nand_boot.c and arch/powerpc/cpu/mpc83xx/nand_init.c.
