Have you tried
u32 value;
pci_write_config_dword(core->bus->host_pci, BCMA_PCI_BAR0_WIN, &value);
pr_info();
pci_write_config_dword(core->bus->host_pci, BCMA_PCI_BAR0_WIN2, &value);
pr_info();

You should also hack bcma_bus_scan to display addr and wrap.
pr_info("Core %d addr: 0x%X, wrap 0x%X\n", core->core_index,
core->addr, core->wrap);
(put is inside the while, after existing pr_info)
