From: Mingkai Hu <mingkai...@freescale.com>
C293PCIE board is a series of Freescale PCIe add-in cards to perform
as public key crypto accelerator or secure key management module.
- 512KB platform SRAM in addition to 512K L2 Cache/SRAM
- 512MB soldered DDR3 32bit memory
- CPLD System Logic
- 64MB x16 NOR flash and 4GB x8 NAND flash
- 16MB SPI flash

Changes for v2:
- Remove the JFFS2 partitions in NOR/NAND/SPI flash;
- Implement the NAND partitions;
- Remove the no use descriptions for cpld node;
- Add mpc85xx_smp_defconfig and mpc85xx_defconfig for C293;
- Remove the no use includes in c293pcie.c
Changes for v3:
- Remove some partitions for NAND, merge them into RFS
- Modify the SPI RFS partition expression
- Remove #address-cells #size-cells in cpld node
