infra/rdn2cfg1: add user guide for rd-n2-cfg1 platform

Add the initial user guide for the RD-N2-Cfg1 platform software stack.
The user guide points to documents that provide information about
obtaining the platform software stack and using the various features it
supports. A table to list the release tags is included as well.

+RD-N2 Cfg1 platform software user guide
+=======================================

+
+
+Introduction
+------------
+
+RD (Reference Design) is a collection of resources to provide a representative
+view of typical compute subsystems that can be designed and implemented using
+specific generations of Arm IP. RD-N2 Cfg1 platform (which is a variant of the
+the `RD-N2`_ platform) in particular is based on the following hardware
+configuration.
+
+- 8xMP1 Neoverse N2 CPUs
+- CMN-700 interconnect (mesh size 3x3)
+- Multiple AXI expansion ports for I/O Coherent PCIe, Ethernet, offload
+- Arm Cortex-M7 for System Control Processor (SCP) and
+  Manageability Control Processor (MCP)
+
+This document is a user guide on how to setup, build and run the RD-N2 Cfg1
+software stack on the Fixed Virtual Platform.
+
+
+Setting up the Host Machine and Syncing the software stack
+----------------------------------------------------------
+
+Host Machine requirements and the necessary steps to be followed to sync the
+software stack are listed on '`Download sources`_' page.
+
+
+Obtaining the RD-N2-Cfg1 FVP
+----------------------------
+
+The latest version of the RD-N2-Cfg1 fixed virtual platform (FVP) can be
+downloaded from the `Arm Ecosystem FVPs`_ page. On this page, navigate to
+"Neoverse Infrastructure FVPs" section to download the RD-N2-Cfg1 platform
+FVP installer.
+
+Follow the instructions of the installer and setup the FVP. The installer, by
+default, selects the home directory to install the FVP. To opt for different
+directory than the one selected by the installer, provide an absolute path to
+that directory when prompted for during the FVP installation process.
+
+
+Supported Features by RD-N2-Cfg1 platform software stack
+--------------------------------------------------------
+
+RD-N2-Cfg1 platform software stack supports the following features.
+
+- `Busybox Boot`_.
+- `Linux Distribution Boot`_.
+- `WinPE Boot`_.
+- `ACS Compliance Test`_.
+- `UEFI Secure Boot`_.
+
+
+Follow the links above for detailed information about the build and execute
+steps for each of the supported features.
+
+
+Release Tags
+------------
+
+Table below lists the release tags for the RD-N2-Cfg1 platform software stack and
+the corresponding RD-N2-Cfg1 FVP version that is recommended to be used along
+with the listed release tag. The summary of the changes introduced and tests
+validated in each release is listed in `change log`_.
