ACRN didn't support dynamic memory allocation. SO it would reserve a big page pool and use the GPA as index to get a page to do EPT mapping. In order to save memory, we put high MMIO windows to [4G, 5G]. AFter we support dynamic page allocation for EPT mapping, we move high MMIO windows to where it used to ([256G, 512G]) for 39 bits physical address), we could move high memory to where is used to too ([4G, 4G + size]).
