Modified Files:
src/sys/arch/arm/nvidia: tegra_pcie.c
Log Message:
Change tegra_pcie_conf_hook() to only give us the defaults without
enabled bus mastering. Previously both bus mastering and ROM decode
were enabled at pci_configure_bus() time. Both bus mastering and ROM
decode potentially have undesireable side effects. These can best be
managed by drivers familiar with their hardware.
