Technically, U-Boot is GPLv2+ so GPLv2 only code _may_ not be accepted That is for Wolfgang to decide, but you have been warned :)
Naturally, he is king after all. There will be a thousand reasons to reject it, but hopefully not due to license.
I based my GITHUB after the CuBox fork of u-boot. I will leave it up to those guys to submit their patches separately.
My fork of u-boot is here:
** https://github.com/lundman/u-boot
To see only the change set for adding ZFS:
** https://github.com/lundman/u-boot/compare/zfs
Since I merged in EXT4 patches to get a feel for u-boot, they are here:
** https://github.com/lundman/u-boot/compare/ext4
Only minor strings changes of "ext2" -> "ext4", otherwise the Samsung patch V4 posted in here.
