New Revision: 366951
URL: https://svnweb.freebsd.org/changeset/base/366951
Log:
loader: revert r342161 and r342151
We are using asize property from pool label and we do not depend
on partition data to find last two pool labels and to validate LBA for disk IO.
This does allow us to re-enable support for partitionless disk setups.
