[U-Boot] OMAP3 Falcon Mode NAND Unlock

I am trying to falcon-mode load from NAND. Unfortunately, I have to unlock the NAND before I can boot. I can run u-boot and script 'nand unlock' into the boot sequence and everything runs.

Is there a simple way to unlock the NAND from withing Falcon mode before jumping to the kernel? I was thinking it should go into spl_board_prepare_for_linux(), but I am not sure how to get the NAND info and size to pass them to nand_unlock()
