Above code sets the BOOLEAN array to all FALSE.
Then polling on the array to be all TRUE.
We need to add "volatile" to the mSmmInitialized to tell
the compiler not to optimize the code but always check the
memory content.
A better way is to use compiler barrier but there is no
edk2 lib API to wrap it for different compilers
Let's just use "volatile" for now.
Thanks,
Ray
