New Revision: 237045
URL: http://svn.freebsd.org/changeset/base/237045
Log:
More Linux boot support. Create arm_dump_avail_init() to initialize
this array either from Linux boot data, when enabled, or in the
typical way that most ports do it. arm_pyhs_avail_init is coming
soon since it must be a separate function.
