| 2019-12-04 | nds32: use pgtable-nopmd instead of 4level-fixup | Mike Rapoport | 1 | -1/+3 | |
| nds32 has only two-level page tables and can use pgtable-nopmd and folding of the upper layers. Replace usage of include/asm-generic/4level-fixup.h and explicit definition of __PAGETABLE_PMD_FOLDED in nds32 with include/asm-generic/pgtable-nopmd.h and adjust page table manipulation macros and functions accordingly.

| 2018-11-06 | nds32: Power management for nds32 | Nick Hu | 1 | -0/+79 | |
| 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.
