From 986691fb97bc245be517a9db1297cfa71dd865cf Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 26 Jan 2016 11:10:13 -0700 Subject: distro bootcmd: enumerate PCI before network operations The PCI bus must be enumerated before PCI devices, such as Ethernet devices, are known to U-Boot. Enhance the distro boot commands to perform PCI enumeration when needed.
