zfs: Add ZFS filesystem support
U-Boot port is based on sources forked from GRUB-0.97 by Sun in 2004, which can be found here: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/grub/grub-0.97/stage2/zfs-include/zfs.h Released by Sun for GRUB under the license: * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. GRUB official releases include ZFS in version: ftp://alpha.gnu.org/gnu/grub/grub-1.99~rc1.tar.gz And patched against GRUB Bazaar repository for ashift fixes (4KB HDDs) more conveniently found at github: https://github.com/pendor/grub-zfs/commit/e7b6ef3ac3b9685ac4c394c897b1d4221b7381f1 Signed-off-by: Jorgen Lundman <lundman@lundman.net>
