| This file declares Vector Handoff Info PPI that describes an array of |
| interrupt and/or exception vectors that are in use and need to persist. |
| |
| This is an optional PPI that may be produced by SEC. If present, it provides |
| a description of the interrupt and/or exception vectors that were established |
| in the SEC Phase and need to persist into PEI and DXE. |
