There could be scenarios where the HOB producer does not create any HOBs. In such cases, the buffer intended to be freed will have zero pages. This update addresses the issue that could cause assertions during runtime by ensuring that buffers with zero pages are not freed.

Current MM IPL in PEI phase does not open the MMRAM regions through MM access PPI. This is causing some platforms like OVMF reading all `0xFF`s when trying to relocate the Standalone MM core. This change opens all the MMRAM regions provided by MM access PPI and closes + locks the regions after initial MM foundation setup, when MM Access PPI is available. Platforms that require MM access PPI can inject depex through libraries. Signed-off-by: Kun Qin <[email protected]> (cherry picked from commit 73b0b5e)
