Sakar Arora July 25, 2017, 6:10 a.m. UTC 
From: Mahesh Bireddy <mahesh.reddybireddy@arm.com>

Server Base Boot Requirements (SBBR) specification is intended for SBSA-
compliant 64-bit ARMv8 servers. It defines the base firmware
requirements for out-of-box support of any ARM SBSA-compatible
Operating System or hypervisor. The requirements in this specification
are expected to be minimal yet complete for booting a multi-core ARMv8
server platform, while leaving plenty of room for OEM or ODM innovations
and design details. For more information, download the SBBR
specification here:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.den0044b/index.html

This change introduces test cases as per SBBR specification to madt acpi table.
