2016-08-04soc/apollolake: Return correct wake status in _SWSShaunak Saha
Wake status is calculated from the four pairs of gpe0 in cbmem CBMEM_ID_POWER_STATE which is filled very early in romstage and depends on the routing information in PMC GPE_CFG register. Coreboot sets the proper value of routing based on devicetree from pmc_init. But when system goes to S3 on waking up PMC is writing default values again in GPE_CFG which results in returning wrong wake status in _SWS. This patch corrects that behaviour by correcting the gpe0 pairs in cbmem after PMC sets the routing table in resume path. BUG=chrome-os-partner:54876 TEST=On resume through powerbtn, lidopen, keyboard press, etc. we are getting proper wake status.
