BCMA bus may have many versions of PCIe core. This driver
supports:
1) PCIe core working in clientmode
2) PCIe Gen 2 clientmode core
In general PCIe (Gen 2) clientmode core is required on PCIe
hosted buses. It's responsible for initialization and basic
hardware management.
This driver is also prerequisite for a hostmode PCIe core
support.

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.
