 /**

-  Entry point to DXE core.

-

-  This function is the entry point to the DXE Foundation. The PEI phase, which executes just before

-  DXE, is responsible for loading and invoking the DXE Foundation in system memory. The only

-  parameter that is passed to the DXE Foundation is HobStart. This parameter is a pointer to the

-  HOB list that describes the system state at the hand-off to the DXE Foundation. At a minimum,

-  this system state must include the following:

-    - PHIT HOB

-    - CPU HOB

-    - Description of system memory

-    - Description of one or more firmware volumes

-  The DXE Foundation is also guaranteed that only one processor is running and that the processor is

-  running with interrupts disabled. The implementation of the DXE Foundation must not make any

-  assumptions about where the DXE Foundation will be loaded or where the stack is located. In

-  general, the DXE Foundation should make as few assumptions about the state of the system as

-  possible. This lack of assumptions will allow the DXE Foundation to be portable to the widest

-  variety of system architectures.

-  

-  @param  HobStart Pointer of HobList.

+  The entry point of PE/COFF Image for the DXE Core. 

+

+  This function is the entry point for the DXE Core.  This function is required

+  to call ProcessModuleEntryPointList() and ProcessModuleEntryPoint() is never

+  expected to return.  The DXE Core is responsible for calling ProcessLibraryConstructorList()

+  as soon as the EFI System Table and the image handle for the DXE Core itself have

+  been established.

+  If ProcessModuleEntryPointList() returns, then ASSERT() and halt the system.

+

+  @param  HobStart  Pointer to the beginning of the HOB List passed in from the PEI Phase.
