New Revision: 235348
URL: http://svn.freebsd.org/changeset/base/235348

Log:
  Add glue/support for the SAM9XE512-based Ethernut 5 boards. Currently,
  all integrated and on-board peripherals except the DataFlash (at91_spi(4)
  and at45d(4) still need to be unb0rken) and NAND Flash (missing NAND
  framework) are working.
  AFAICT, this makes FreeBSD the first operating system besides Nut/OS
  supporting Ethernut 5 out of tree.
