hose_list is in pci-common.c which is built when PCI=y.
PSERIES and POWERNV force PCI=y.
But this config has neither:
# CONFIG_PPC_POWERNV is not set
# CONFIG_PPC_PSERIES is not set
CONFIG_HAVE_PCI=y
# CONFIG_PCI is not set
# CONFIG_COMMON_CLK_RS9_PCIE is not set
Probably the spapr_tce code should be wrapped in an #ifdef that is only
enabled when POWERNV || PSERIES is enabled.
cheers
