This patch adds the Freescale MPC86xADS board support. The supported devices are SMC UART and 10Mbit ethernet on SCC1. The manual for the board says that it "is compatible with the MPC8xxFADS for software point of view". That's why this patch extends FADS instead of introducing a new platform. FEC is not supported as the "combined FCC/FEC ethernet driver" driver by Pantelis Antoniou should replace the current FEC driver.
