| 2 | Implement this to add SBE dump management. |

| 4 | Self Boot Engine(SBE) is a microcontroller that sits inside the processor to |
| 5 | initialize it to start the booting and also acts as a secure channel for |
| 6 | accessing certain control functions on the processor. During the booting or |
| 7 | other hardware access operations SBE can encounter errors and become |
| 8 | unresponsive. In such situations, the debug data needs to be collected from |
| 9 | such SBEs to find out the root cause of the error. This data includes |
| 10 | hardware state, configuration, memory, etc. The collected data is then |
| 11 | packaged into the OpenPOWER dump format and which is called as SBE dump. |
| 12 | There will be one instance of SBE on each processor. Implement this |
| 13 | interface to add support for managing the SBE dump. |
