  45           BCMA bus may have many versions of PCIe core. This driver

  48           2) PCIe Gen 2 clientmode core

  50           In general PCIe (Gen 2) clientmode core is required on PCIe
  51           hosted buses. It's responsible for initialization and basic
  52           hardware management.
  53           This driver is also prerequisite for a hostmode PCIe core

  81           Some cheap devices have serial flash connected to the ChipCommon
  82           instead of independent SPI controller. It requires using a separated
  83           driver that implements ChipCommon specific interface communication.

  85           Enabling this symbol will let bcma recognize serial flash and register
