REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1485 Current FSP utilizes pre-allocated temporary memory from boot loader for both heap and stack. To reduce overall temporary memory usage FSP may share the same stack with boot loader and only needs a smaller memory for heap, no separate memory required for stack. Setting PcdFspHeapSizePercentage to 0 to enable FSP sharing stack with boot loader, in this case boot loader stack has to be large enough for FSP to use. Default is 50 (half memory heap and half memory stack) for backward compatible with original model. Test: Verified on internal platform and booting successfully with both modes.
