Cover letter [PATCH v3 0/2] socfpga: fix hotplug/add suspend to ram
From: Alan Tull <[email protected]>
Patch 1: socfpga: hotplug: put cpu1 in wfi
Use WFI when putting CPU1 to sleep. Don't hold CPU1 in reset since that results in increased power consumption. Only briefly reset CPU1.
Patch 2: socfpga: support suspend to ram
* allocate space in ocram using sram driver
* Add a function in ocram to do suspend to ram and place DDR in self-refresh
