Poonam Aggrwal [Fri, 7 Aug 2009 15:35:16 +0000 (20:35 +0530)]
Add support for the P2020RDB reference board from Freescale.

Overview of P2020RDB platform
- DDR
  DDR2 1G
- NOR Flash
  16MByte
- NAND Flash
  32MByte
- 3 Ethernet interfaces
  1) etSEC1
- RGMII
- connected to a 5 port Vitesse Switch(VSC7385)
- Switch is memory mapped through eLBC interface(CS#2)
- IRQ1
  2) etSEC2
- SGMII
- connected to VSC8221
- IRQ2
  3) etSEC3
- RGMII
- connected to VSC8641
- IRQ3
- 2 1X PCIe interfaces
- SD/MMC ,USB
- SPI EEPROM
- Serial I2C EEPROM
