powerpc/85xx: Add basic support for P1010RDB
Boot methods supported: NOR Flash, SPI Flash and SDCARD This patch adds the following basic interfaces: DDR3, eTSEC, DUART, I2C, SD/MMC, USB, SATA, PCIe, NOR Flash, SPI Flash. P1010RDB Overview ----------------- 1Gbyte DDR3 (on board DDR) Local Bus (IFC): 32Mbyte 16bit NOR flash 32Mbyte SLC NAND Flash 64KB CPLD device(GPCM interface) SPI Flash: 128 Mbit SPI Flash memory SD/MMC: connector to interface with the SD memory card SATA: 1 internal SATA connect to 2.5. 160G SATA2 HDD 1 eSATA connector to rear panel USB 2.0: x1 USB 2.0 port: connected via a UTMI PHY to Mini-AB interface. x1 USB 2.0 port: directly connected to Mini-AB interface Ethernet eTSEC: eTSEC1: Connected to RGMII PHY VSC8641XKO eTSEC2: Connected to SGMII PHY VSC8221 eTSEC3: Connected to SGMII PHY VSC8221 eCAN: Two DB-9 female connectors for Field bus interface UART: supports two UARTs up to 115200 bps for console TDM: 2 FXS ports connected via an external SLIC to the TDM interface. SLIC: SPI SLIC I2C: Serial EEprom Real time clock 256 Kbit M24256 I2C EEPROM PCIe: PCIe and mPCIe connectors.
