From f05970380e4c72a198cce29affc622a8e543b4de Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 8 Apr 2020 08:32:59 -0600 Subject: [PATCH] pci: Add a macro to convert BDF from linux to U-Boot U-Boot's BDF format has its bits in the same position as the device tree PCI definition. Some x86 devices use linux format in their register format and it is useful to be able to convert to U-Boot format. Add a macro for this.
