REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3473 X64 Reset Vector Code can access the memory range till 4GB using the Linear-Address Translation to a 2-MByte Page, when user wants to use more than 4G using 2M Page it will leads to use more number of Page table entries. using the 1-GByte Page table user can use more than 4G Memory by reducing the page table entries using 1-GByte Page, this patch attached can access memory range till 512GByte via Linear- Address Translation to a 1-GByte Page. Build Tool: if the nasm is not found it will throw Build errors like FileNotFoundError: [WinError 2]The system cannot find the file specified run the command wil try except block to get meaningful error message Test Result: Tested in both Simulation environment and Hardware both works fine without any issues.
