New Revision: 238742
URL: http://svn.freebsd.org/changeset/base/238742
Log:
Update to latest git version of dtc to get new dtsv2 support,
including the include directive.
Fix minor build issue corrected by converting yypush_buffer_state and
yypop_buffer_state to yy_set_buffer_state and a hard-coded 100-deep
stack. It was easier to fix it here than to import that support into
our flex.
The new tools and test hardness remain unsupported at the moment.
