From bef75e7dd9450679d1605df8326a4dfbf2800ff9 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 26 May 2016 11:00:44 -0500 Subject: soc/intel/apollolake: add support for verstage There previously was no support for building verstage on apollolake. Add that suport by linking in the appropriate modules as well as providing vboot_platform_is_resuming(). The link address for verstage is the same as FSP-M because they would never be in CAR along side each other. Additionally, program the ACPI I/O BAR and enable decoding so sleep state can be determined for early firmware verification.
