Call for action

In order to support SMM memory protection, the firmware need configure SMM driver to be page aligned:

1. Override link flags below to support SMM memory protection.

     [BuildOptions.common.EDKII.DXE_SMM_DRIVER,
     BuildOptions.common.EDKII.SMM_CORE]    
     MSFT:*_*_*_DLINK_FLAGS = /ALIGN:4096 
     GCC:*_*_*_DLINK_FLAGS = -z common-page-size=0x1000
   

2. Evaluate if SMRAM size is big enough.
