New Revision: 335564
URL: https://svnweb.freebsd.org/changeset/base/335564

Log:
  Add spigen(4) fdt data overlays for RPI-B, RPI-2.
  
  By adding spigen-rpi{2,-b}.dtso to fdt_overlays= in loader.conf, the fdt data
  will set up the correct pinmux and device nodes to create a spigen(4) device
  for each available chipselect pin.
