powerpc/t1023rdb: Add T1023 RDB board support
T1023RDB is a Freescale Reference Design Board that hosts the T1023 SoC. T1023RDB board Overview ----------------------- - T1023 SoC integrating two 64-bit e5500 cores up to 1.4GHz - CoreNet fabric supporting coherent and noncoherent transactions with prioritization and bandwidth allocation - Memory: 2GB Micron MT40A512M8HX unbuffered 32-bit fixed DDR4 without ECC - Accelerator: DPAA components consist of FMan, BMan, QMan, DCE and SEC - Ethernet interfaces: - one 1G RGMII port on-board(RTL8211F PHY) - one 1G SGMII port on-board(RTL8211F PHY) - one 2.5G SGMII port on-board(AQR105 PHY) - PCIe: Two Mini-PCIe connectors on-board. - SerDes: 4 lanes up to 10.3125GHz - NOR: 128MB S29GL01GS110TFIV10 Spansion NOR Flash - NAND: 512MB S34MS04G200BFI000 Spansion NAND Flash - eSPI: 64MB S25FL512SAGMFI010 Spansion SPI flash. - USB: one Type-A USB 2.0 port with internal PHY - eSDHC: support SD/MMC card and eMMC on-board - 256Kbit M24256 I2C EEPROM - RTC: Real-time clock DS1339 on I2C bus - UART: one serial port on-board with RJ45 connector - Debugging: JTAG/COP for T1023 debugging As well updated T1024RDB to add T1023RDB.
