| Description: These files allow asserting system power cycling, switching |
| power supply units on and off and system's main power domain |
| shutdown. |
| Expected behavior: |
| When pwr_cycle is written 1: auxiliary power domain will go |
| down and after short period (about 1 second) up. |
| When psu1_on or psu2_on is written 1, related unit will be |
| disconnected from the power source, when written 0 - connected. |
| If both are written 1 - power supplies main power domain will |
| go down. |
| When pwr_down is written 1, system's main power domain will go |
| down. |
| |
| The files are write only. |
