Updating u-boot on NAND

How would I update a u-boot on my Cubietruck?
I want to update it to 2014.10+ version for it to have an AHCI boot support to boot directly from the hard drive.
I know I could use sd card to store uboot and configure it to boot from hdd, but I don't want to do that. Instead I want to somehow put uboot update into the nand.

Damn, I figured out I cant reflash the bundled u-boot. It's not on nand, it's on chip, somewhere else.

The next idea is to boot initramfs from nand, mount HDD and then kexec to kernel on HDD.
Have anyone do that?

Where did you find the info that the uboot on the board can't be updated?

Can sb confirm this info?
