bc2d40ca10 board/p1_p2_rdb:Enable p1_p2_rdb boot from NAND/SD/SPI in SPL
In the earlier patches, the SPL/TPL fraamework was introduced.
For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The
SPL was loaded by the code from the internal on-chip ROM. The SPL initializes
the DDR according to the SPD and loads the final uboot image into DDR, then
jump to the DDR to begin execution.

For NAND booting way, the nand SPL has size limitation on some board(e.g.
P1010RDB), it can not be more than 4KB, we can call it "minimal SPL", So the
dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is
loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD
and loads the final uboot image into DDR,then jump to the DDR to begin execution.

This patch enabled SPL/TPL for P1_P2_RDB to support starting from NAND/SD/SPI
flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL.
Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to
execute, so the section .resetvec is no longer needed.

0c871e952e powerpc/85xx: Use DDR for RAMBOOT instead of L2 SRAM on p1_p2_rdb
Using DDR as RAMBOOT base instead of L2SRAM for SDCard and SPI Flash
boot loaders because:
- P1_P2_RDB boards have soldered DDR so no need for SPD
- Also P102x has 256K L2 cache size so becomes a limiting factor for
  size of image that could be loaded in SRAM mode and would require three
  stage boot loader (TPL).

Changes done:
 1. CONFIG_SYS_TEXT_BASE to 0x11000000
 2. CONFIG_RESET_VECTOR_ADDRESS to 0x1107fffc

b0c5ceb305 powerpc/85xx: Fix PCI memory map setup on P1_P2_RDB
Update the PCIe address map to match standard FSL memory map.
Additionally, fix the TLBs so the cover the PCIe address space properly
so cards plugged in like an e1000 work correctly.

We already map the page cache-inhibited.  There is no reason we
shouldn't also be marking it guarded to prevent speculative accesses.

728ece343e 85xx: Add support for P2020RDB board
The code base adds P1 & P2 RDB platforms support.
The folder and file names can cater to future SOCs of P1/P2 family.
P1 & P2 processors are 85xx platforms, part of Freescale QorIQ series.

Tested following on P2020RDB:
1. eTSECs
2. DDR, NAND, NOR, I2C.
