Subject: imx: ventana: default msata/pci mux to pci before PCI enumeration
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=77c550189369eeb82f2a67681b343dea68809e62;p=project%2Fbcm63xx%2Fu-boot.git

imx: ventana: default msata/pci mux to pci before PCI enumeration

PCI enumeration occurs early, before we fully configure our GPIO's. Make
sure we steer the MSATA/PCI mux to PCI in board_init to ensure PCI is
selected before enumeration.
