    pstore/ram: add Device Tree bindings · 35da6094

    ramoops is one of the remaining places where ARM vendors still rely on
    board-specific shims.  Device Tree lets us replace those shims with
    generic code.
    These bindings mirror the ramoops module parameters, with two small
    (1) dump_oops becomes an optional "no-dump-oops" property, since ramoops
        sets dump_oops=1 by default.
    (2) mem_type=1 becomes the more self-explanatory "unbuffered" property.
