New Revision: 238415
URL: http://svn.freebsd.org/changeset/base/238415

Log:
  For our at91rm9200 boards, register which subtype of SoC is on the
  board.  We'll use this later to control the differences between these
  two variants' pins.

Added:
  head/sys/arm/at91/at91rm9200_devices.c   (contents, props changed)
  head/sys/arm/at91/at91rm9200var.h   (contents, props changed)
Modified:
