spl: fix build failure with !CONFIG_SPL_PCI_SUPPORT 2018-12-12T17:14:23+00:00 Sekhar Nori nsekhar@ti.com 2018-12-06T10:10:08+00:00 d50d6817b583d20bf1c6e26c656d125bde5e4e4b Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but CONFIG_SPL_PCI_SUPPORT disabled, results in following linker error: lib/built-in.o: In function `fdtdec_get_pci_bar32': lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32' fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32' This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c while SPL build does not descend into drivers/pci directory in drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled.
