powerpc/85xx: introduce support for the Freescale / iVeia P1022RDK
The Freescale / iVeia P1022RDK reference board is a small-factor board with a Freescale P1022 SOC. It includes: 1) 512 MB 64-bit DDR3-800 (max) memory 2) 8MB SPI serial flash memory for boot loader 3) Bootable 4-bit SD/MMC port 4) Two 10/100/1000 Ethernet connectors 5) One SATA port 6) Two USB ports 7) One PCIe x4 slot 8) DVI video connector 9) Audio input and output jacks, powered by a Wolfson WM8960 codec. Unlike the P1022DS, the P1022RDK does not have any localbus devices, presumably because of the localbus / DIU multiplexing restriction of the P1022 SOC.
