PCI: designware: Don't complain missing *config* reg space if va_cfg0 is set
Currently on Keystone SoCs, we always complain: keystone-pcie 21021000.pcie: missing *config* reg space Keystone uses an older version of DesignWare hardware that doesn't have ATU support. So va_cfg0_base and va_cfg1_base are already set up in ks_dw_pcie_host_init() before calling dw_pcie_host_init(), and they point to the remote config space address va (both same for Keystone). Add a check to avoid this boot noise on Keystone. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
