| * ChipTOD (aka TOD) is a facility implemented in the nest / pervasive. The |
| * purpose is to keep time-of-day across chips and cores. |
| * |
| * There is a master chip TOD, which sends signals to slave chip TODs to |
| * keep them synchronized. There are two sets of configuration registers |
| * called primary and secondary, which can be used fail over. |
| * |
| * The chip TOD also distributes synchronisation signals to the timebase |
| * facility in each of the cores on the chip. In particular there is a |
| * feature that can move the TOD value in the ChipTOD to and from the TB. |
| * |
| * Initialisation typically brings all ChipTOD into sync (see tod_state), |
| * and then brings each core TB into sync with the ChipTODs (see timebase |
| * state and TFMR). This model is a very basic simulation of the init sequence |
| * performed by skiboot. |
