This builds on the modular EFI loader support added r294060 adding a module to provide ZFS boot support on EFI systems. It should be noted that EFI uses a fixed size memory block for all allocations performed by the loader so it may be necessary to tune this size. For example when building an image which uses mfs_root e.g. mfsbsd, adding the following to /etc/make.conf would be needed to prevent EFI from running out of memory when loading the mfs_root image.
