OK. But the original code may already result in some non-page aligned
memory to be discarded, should that be described as well? Or should
the EfiConventionalMemory HOB cover full pages only?
Now, MdePkg\Library\PeiMemoryAllocationLib AllocateAlignedPages() uses
this way to describe extra memory space.
Thanks,
