/**

Returns the pointer to the HOB list.
|
|
|
|
This function returns the pointer to first HOB in the list.
|
|
For PEI phase, the PEI service GetHobList() can be used to retrieve the pointer
|
|
to the HOB list. For the DXE phase, the HOB list pointer can be retrieved through
|
|
the EFI System Table by looking up theHOB list GUID in the System Configuration Table.
|
|
Since the System Configuration Table does not exist that the time the DXE Core is
|
|
launched, the DXE Core uses a global variable from the DXE Core Entry Point Library
|
|
to manage the pointer to the HOB list.
|
|
|
|
If the pointer to the HOB list is NULL, then ASSERT().
|

@return The pointer to the HOB list.
