When autoport is run on a system without supported southbridge it won't populate the coresponding data structure. By sanitiy checking after PCI detection autoport can exit cleanly and provide a sufficient error message. Error was: panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x30 pc=0x4be595] goroutine 1 [running]: main.FIXMEEC(0xc42014af80, 0x14, 0xc42014afe0, 0x1a, 0xc4200a914f, 0x4, 0xc4200a916f, 0xf, 0xc420149e60, 0x28, ...) /coreboot/util/autoport/ec_fixme.go:14 +0x105 Change-Id: I6b0fcda76d33b0d3a0379c279f492160ce5add84 Signed-off-by: Maximilian Schander <maxschander@googlemail.com> Reviewed-on: https://review.coreboot.org/22203 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net>
