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 Signed-off-by: Mingkai Hu <Mingkai.Hu@freescale.com> Signed-off-by: Po Liu <Po.Liu@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
