This patch builds on the previous patch by implementing support for reading NS DRAM layout of FVP model from HW_CONFIG Device tree. Macro _RMMD_MANIFEST_VERSION is renamed to SET_RMMD_MANIFEST_VERSION to suppress MISRA-C "rule MC3R1.D4.5: (advisory) Identifiers in the same name space with overlapping visibility should be typographically unambiguous" warning Signed-off-by: AlexeiFedorov <Alexei.Fedorov@arm.com> Change-Id: Ifc2461b4441a1efdd4b7c656ab4d15e62479f77b
