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.
