From 5881f8ae3658bf3a4d5bf13a6b9c4c092c08a997 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Wed, 17 Jan 2024 22:00:13 +0100 Subject: soc/amd/common,genoa_poc/domain: rework check for 1st domain Previously the code checked if the first downstream bus of the domain was bus 0 in segment group 0 to only run certain code for the first domain. Instead check if the domain number is 0 which should make the code a bit easier to understand.
