Enrty 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.
