CONFIG_MEDIA_PCI_SUPPORT=y
CONFIG_PCI_ATS=y
CONFIG_PCI_BUS_ADDR_T_64BIT=y
CONFIG_PCI_DEBUG=y
CONFIG_PCI_DMA_32=y
CONFIG_PCI_DOMAINS_GENERIC=y
CONFIG_PCI_DOMAINS=y
CONFIG_PCIEAER=y
CONFIG_PCIEASPM_DEFAULT=y

Here are the settings we currently do NOT have in my RV kernel:

CONFIG_HOTPLUG_PCI_PCIE=y
CONFIG_HOTPLUG_PCI=y
CONFIG_MEDIA_PCI_SUPPORT=y
CONFIG_PCI_ATS=y
CONFIG_PCI_DEBUG=y
CONFIG_PCIEAER=y
CONFIG_PCIEASPM_DEFAULT=y
CONFIG_PCIEASPM=y
CONFIG_PCI_ECAM=y
CONFIG_PCIE_MICROSEMI=y
CONFIG_PCI_ENDPOINT=y
CONFIG_PCIEPORTBUS=y
CONFIG_PCI_HOST_COMMON=y
CONFIG_PCI_HOST_GENERIC=y
CONFIG_PCI_IOV=y
CONFIG_PCI_PASID=y
CONFIG_PCI_PRI=y
CONFIG_PCI_SW_SWITCHTEC=y
CONFIG_USB_BDC_PCI=y

If you're happy with it, I can add all of those.  If there are any
which shouldn't be added let me know.

Rich.
