  46          BCMA bus may have many versions of PCIe core. This driver
  47          supports:
  48          1) PCIe core working in clientmode
  49          2) PCIe Gen 2 clientmode core
  50
  51          In general PCIe (Gen 2) clientmode core is required on PCIe
  52          hosted buses. It's responsible for initialization and basic
  53          hardware management.
  54          This driver is also prerequisite for a hostmode PCIe core
  55          support.

  82          Some cheap devices have serial flash connected to the ChipCommon
  83          instead of independent SPI controller. It requires using a separated
  84          driver that implements ChipCommon specific interface communication.
  85
  86          Enabling this symbol will let bcma recognize serial flash and register
  87          it as platform device.
