[PATCH 1/2] powerpc/85xx: Add P1024rdb board support

From: <hidden>
Date: 2011-12-28 03:42:01

From: Tang Yuantian <redacted>

The p1024rdb has the similar feature as the p1020rdb. Therefore, p1024rdb use
the same platform file as the p1/p2 rdb board.
Overview of P2020RDB platform
	- DDR3 1G
	- NOR flash 16M
	- 3 Ethernet interfaces
	- NAND Flash 32M
	- SPI EEPROM 16M
	- SD/MMC
	- 2 USB ports
	- 4 TDM ports

[PATCH 2/2] powerpc/85xx: Adds Support for P2020RDB-PC board

From: <hidden>
Date: 2011-12-28 03:42:01

From: Tang Yuantian <redacted>

P2020RDB-PC Board shares the same design(PCB) as P102x RDB style platforms.
The difference between this platform and the already existing P2020RDB
is mainly with respect to DDR. The P2020RDB-PC has a DDR3 memory.
The P2020RDB-PC also has a CPLD device connected to local bus.

The main differences from the P102x RDB-PC is 64-bit DDR and SYSCLK of
100Mhz.
