Nick Hu 7938e6315c nds32: Power management for nds32 ... There are three sleep states in nds32: suspend to idle, suspend to standby, suspend to ram In suspend to ram, we use the 'standby' instruction to emulate power management device to hang the system util wakeup source send wakeup events to break the loop. First, we push the general purpose registers and system registers to stack. Second, we translate stack pointer to physical address and store to memory to save the stack pointer. Third, after write back and invalid the cache we hang in 'standby' intruction. When wakeup source trigger wake up events, the loop will be break and resume the system.
