[edk2-devel] [edk2-platforms][PATCH V1 1/3] Platform/Sgi: refactor StandaloneMM platform description file
Posted by Sayanta Pattanayak 4 years, 8 months ago 
The RD-N2 platform has a different memory map from that of the other
platforms supported under the SgiPkg. To enable the use of StandaloneMM
as a secure partition on RD-N2 platform, refactor the existing
StandaloneMM platform description file. The differing portions are split
into two different files and the rest of the  platform description file
is converted into a include file.
