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