+Overview
+--------
+The LS2085A Reference Design (RDB) is a high-performance computing,
+evaluation, and development platform that supports the QorIQ LS2085A
+Layerscape Architecture processor.
+
+LS2085A SoC Overview
+------------------
+The LS2085A integrated multicore processor combines eight ARM Cortex-A57
+processor cores with high-performance data path acceleration logic and network
+and peripheral bus interfaces required for networking, telecom/datacom,
+wireless infrastructure, and mil/aerospace applications.
+
+The LS2085A SoC includes the following function and features:
+
+ - Eight 64-bit ARM Cortex-A57 CPUs
+ - 1 MB platform cache with ECC
+ - Two 64-bit DDR4 SDRAM memory controllers with ECC and interleaving support
+ - One secondary 32-bit DDR4 SDRAM memory controller, intended for use by
+ the AIOP
+ - Data path acceleration architecture (DPAA2) incorporating acceleration for
+ the following functions:
+ - Packet parsing, classification, and distribution (WRIOP)
+ - Queue and Hardware buffer management for scheduling, packet sequencing, and
+ congestion management, buffer allocation and de-allocation (QBMan)
+ - Cryptography acceleration (SEC) at up to 10 Gbps
+ - RegEx pattern matching acceleration (PME) at up to 10 Gbps
+ - Decompression/compression acceleration (DCE) at up to 20 Gbps
+ - Accelerated I/O processing (AIOP) at up to 20 Gbps
+ - QDMA engine
+ - 16 SerDes lanes at up to 10.3125 GHz
+ - Ethernet interfaces
+ - Up to eight 10 Gbps Ethernet MACs
+ - Up to eight 1 / 2.5 Gbps Ethernet MACs
+ - High-speed peripheral interfaces
+ - Four PCIe 3.0 controllers, one supporting SR-IOV
+ - Additional peripheral interfaces
+ - Two serial ATA (SATA 3.0) controllers
+ - Two high-speed USB 3.0 controllers with integrated PHY
+ - Enhanced secure digital host controller (eSDXC/eMMC)
+ - Serial peripheral interface (SPI) controller
+ - Quad Serial Peripheral Interface (QSPI) Controller
+ - Four I2C controllers
+ - Two DUARTs
+ - Integrated flash controller (IFC 2.0) supporting NAND and NOR flash
+ - Support for hardware virtualization and partitioning enforcement
+ - QorIQ platform's trust architecture 3.0
+ - Service processor (SP) provides pre-boot initialization and secure-boot
+ capabilities
+

+Memory map from core's view
+----------------------------
+0x00_0000_0000 .. 0x00_000F_FFFF Boot Rom
+0x00_0100_0000 .. 0x00_0FFF_FFFF CCSR
+0x00_1800_0000 .. 0x00_181F_FFFF OCRAM

+0x05_1000_0000 .. 0x05_FFFF_FFFF IFC region #2
+0x80_8000_0000 .. 0xFF_FFFF_FFFF DDR region #2
+
+Other addresses are either reserved, or not used directly by u-boot.
+This list should be updated when more addresses are used.
+
+IFC region map from core's view
+-------------------------------
+During boot i.e. IFC Region #1:-
+ 0x30000000 - 0x37ffffff : 128MB : NOR flash
+ 0x3C000000 - 0x40000000 : 64MB : CPLD
+
+After relocate to DDR i.e. IFC Region #2:-
+ 0x5_1000_0000..0x5_1fff_ffff Memory Hole
+ 0x5_2000_0000..0x5_3fff_ffff IFC CSx (CPLD, NAND and others 512MB)
+ 0x5_4000_0000..0x5_7fff_ffff ASIC or others 1GB
+ 0x5_8000_0000..0x5_bfff_ffff IFC CS0 1GB (NOR/Promjet)
+ 0x5_C000_0000..0x5_ffff_ffff IFC CS1 1GB (NOR/Promjet)
+
+Booting Options
+---------------
+a) NOR boot
+b) NAND boot
