From d00d682670e1cf5c031a57274d7c4242f7a8193d Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Mon, 31 Jul 2017 10:44:09 +0530 Subject: [PATCH] soc/intel/skylake: Skip disabled IGD device If IGD PCI device is disabled: 1. BAR for the device will be 0. 2. There is no need to allocate framebuffer for this device. Some early SOCs don't have GFX model fuse by default hence we need to add a check to ensure PCI device is enable. This code to avoid die inside coreboot for missing resources.
