Mingkai Hu 622e03eb34 powerpc/85xx: Add C293PCIE board support
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
