Mips builds with BCMA host mode enabled fail in mainline and -next
with:
In file included from include/linux/bcma/bcma.h:10:0,
from drivers/bcma/bcma_private.h:9,
from drivers/bcma/main.c:8:
include/linux/bcma/bcma_driver_pci.h:218:24: error:
field 'pci_controller' has incomplete type
Bisect points to commit d41e6858ba ("MIPS: Kconfig: Set default MIPS
system type as generic") as the culprit. Analysis shows that the commmit
changes PCI configuration and enables PCI_DRIVERS_GENERIC. This in turn
disables PCI_DRIVERS_LEGACY. 'struct pci_controller' is, however, only
defined if PCI_DRIVERS_LEGACY is enabled.
Ultimately that means that BCMA_DRIVER_PCI_HOSTMODE depends on
PCI_DRIVERS_LEGACY. Add the missing dependency.
Fixes: d41e6858ba ("MIPS: Kconfig: Set default MIPS system type as ...")

Some cheap devices have serial flash connected to the ChipCommon

instead of independent SPI controller. It requires using a separated

driver that implements ChipCommon specific interface communication.

Enabling this symbol will let bcma recognize serial flash and register

it as platform device.
