From f1f4438218d4d042fd36431dd5ff382c0a9f7a2c Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 26 Apr 2020 09:12:56 -0600 Subject: [PATCH] pci: Avoid auto-config when chain loading When U-Boot is not the first-stage bootloader we don't want to re-configure the PCI devices, since this has already been done. Add a check to avoid this.
