From 55380631f4d02dc06bbdf2295d5c2df8deac9b5b Mon Sep 17 00:00:00 2001 From: Felix Held Date: Fri, 12 Jan 2024 00:05:12 +0100 Subject: [PATCH] soc/amd/common/data_fabric/domain: write _SEG method in SSDT As a preparation for the multi PCI segment group support, use acpigen_write_BBN to generate the _SEG method that returns the segment group number of the PCI root. Until the multi PCI segment group support is enabled in coreboot, it will always return 0.
