+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.

+ - 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

+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)
