Initial import of AR2315 support, specifically the Meraki Mini (see
the Meraki web site at http://www.meraki.net/ ) This includes changes to the AR5312 to make it more conducive to sharing code with the AR5315, and also includes improved early console support. All devices including ethernet and wlan interfaces on the Meraki Mini are functional with this port, _except_ SPI flash, which will be introduced later. This port was funded by the Champaign-Urbana Communit Wireless Network Project (CUWiN).
