[U-Boot] How to make a bootable NAND for A20-OLinuXino-LIME

Hello,

I am trying to make a bootable NAND for A20-OLinuXino-LIME.

My understanding is that there is not yet support for this card. Is it exact ? When will it be available ?

If it is possible now, do you have instructions on how to build u-boot-sunxi for A20-OLinuXino-LIME ?

I found that there was a lichee-dev-a20 branch but I did not find the make target (boardtype) for A20-OLinuXino. Does it exist ?

Thank you in advance

Laurent
