All primary platforms default to LRA now, not the old reload. It is too early to remove reload (and all ports still using reload ;-) ), this will take time, but as a first step this series makes LRA used by default.
It should not change behaviour for any existing port, only for new ports. After the patches, ports that always want LRA do not have to define anything, where currently ports that never want LRA define nothing. This series is not exhaustively tested. Is it okay for trunk though? Segher
