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.
