+# TP Link MR3020 - an AR9331 based SoC wifi device.
+#
+# This is for the 32 RAM/4 flash part. There is little to no
+# chance that this will ever boot FreeBSD directly from the 3.5MB
+# of flash.  The kernel can fit into the space, but userland is just
+# too big even when stripped down to its limits.
