2. Added SwitchIplStacks() function to DxeIplPeim to encapsulate arch details on stack switching. 3. Added PeiSwitchStacks() function to PeiMain to encapsulate arch details on stack switching. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@1328 6f19259b-4bc3-4df7-8a09-765794883524

| Routine Description:

| 
 | |
|   Creates architecture-specific HOBs.
 | |
| 
 | |
|   Note: New parameters should NOT be added for any HOBs that are added to this
 | |
|         function.  BspStore is a special case because it is required for the
 | |
|         call to SwitchStacks() in DxeLoad().
 | |
| 
 | |
| Arguments:
 | |
| 
 | |
|   BspStore    - The address of the BSP Store for those architectures that need
 | |
|                 it.  Otherwise 0.
 | |
| 
 | |
| Returns:
 | |
| 
 | |
|   EFI_SUCCESS   - The HOBs were created successfully.
