Subject: Import partial support for the IQ31244 eval board (i80321 CPU).
 IQ80321 might work out of the box too, but I have no hardware to test. It
 works well enough to go multiuser. Network works, SATA does not, as I have no
 drive to test. Thanks to Intel for sending such a board.

Obtained from:  NetBSD
