| 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. | |
