Add support for Freescale T1024/T1023 SoC. The T1024 SoC includes the following function and features: - Two 64-bit Power architecture e5500 cores, up to 1.4GHz - private 256KB L2 cache each core and shared 256KB CoreNet platform cache (CPC) - 32-/64-bit DDR3L/DDR4 SDRAM memory controller with ECC and interleaving support - Data Path Acceleration Architecture (DPAA) incorporating acceleration - Four MAC for 1G/2.5G/10G network interfaces (RGMII, SGMII, QSGMII, XFI) - High-speed peripheral interfaces - Three PCI Express 2.0 controllers - Additional peripheral interfaces - One SATA 2.0 controller - Two USB 2.0 controllers with integrated PHY - Enhanced secure digital host controller (SD/eSDHC/eMMC) - Enhanced serial peripheral interface (eSPI) - Four I2C controllers - Four 2-pin UARTs or two 4-pin UARTs - Integrated Flash Controller supporting NAND and NOR flash - Two 8-channel DMA engines - Multicore programmable interrupt controller (PIC) - LCD interface (DIU) with 12 bit dual data rate - QUICC Engine block supporting TDM, HDLC, and UART - Deep Sleep power implementaion (wakeup from GPIO/Timer/Ethernet/USB) - Support for hardware virtualization and partitioning enforcement - QorIQ Platform's Trust Architecture 2.0 Differences between T1024 and T1023: Feature T1024 T1023 QUICC Engine: yes no DIU: yes no Deep Sleep: yes no I2C controller: 4 3 DDR: 64-bit 32-bit IFC: 32-bit 28-bit Signed-off-by: Shengzhou Liu <Shengzhou.Liu@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
