The pci_indirect.c file is always compiled when CONFIG_PCI is defined although the indirect PCI bridge support is not needed by every board. Introduce a new CONFIG_PCI_INDIRECT_BRIDGE config option and only compile indirect PCI bridge support if this options is enabled. Also add the new option into the configuration files of the boards which needs that. Compile tested for powerpc, x86, arm and nds32. MAKEALL results: powerpc: --------------------- SUMMARY ---------------------------- Boards compiled: 641 Boards with warnings but no errors: 2 ( ELPPC MPC8323ERDB ) ---------------------------------------------------------- Note: the warnings for ELPPC and MPC8323ERDB are present even without the actual patch. x86: --------------------- SUMMARY ---------------------------- Boards compiled: 1 ---------------------------------------------------------- arm: --------------------- SUMMARY ---------------------------- Boards compiled: 311 ---------------------------------------------------------- nds32: --------------------- SUMMARY ---------------------------- Boards compiled: 3 ---------------------------------------------------------- Cc: Tom Rini <trini@ti.com> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com> Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
