From a platform board perspective, the SoC initiates a Warm Reset sequence while in 

the S0 (Working) state. The situations when this occurs are shown as Reset Type 1 in 

.

A Warm Reset sequence is the same as the Cold Reset except that the SoC SUS well, 

DDR3 power, and Core well power remain on during the entire sequence. The platform 

also provides valid reference clocks to the SoC during the entire Warm Reset sequence. 

Refer to 

:

1. The SoC issues a Platform Reset (PMU_PLTRST_B).
2. The SoC remains in the S0 (Working) state.
3. The SoC ends the Platform Reset.
4. The SoC re-boots the BIOS and operating system.
